Abstract:
Compared with electroplating, liquid casting enables the rapid formation of a three-dimensional solenoid coil with a narrower line width and greater thickness, which proves advantageous in enhancing the comprehensive performance of the micro-electromechanical system (MEMS) fluxgate sensor. For this reason, a MEMS fluxgate sensor based on liquid casting with a closed-loop Fe-based amorphous alloy core is proposed. Based on the process parameters of liquid casting, the structure of the MEMS fluxgate sensor was designed. Utilizing MagNet to build the simulation model, the optimal excitation conditions and sensitivity were obtained. According to the simulation model, a highly sensitive MEMS fluxgate sensor based on liquid casting was fabricated. The resulting sensor exhibits a sensitivity of 2847 V/T, a noise of 306 pT/√Hz@1 Hz, a bandwidth of DC-10.5 kHz, and a power consumption of 43.9 mW, which shows high sensitivity and low power consumption compared with other MEMS fluxgates in similar size.

Abstract:
Current fluxgate sensor probe SPICE models constructed by using arc tangent transfer function method and the diode model in fluxgate sensor simulation had some disadvantages which were non convergence, low simulation accuracy, discontinuously adjusted core characteristics and the model couldn’t simulate the hysteresis characteristic. IO characteristics of Schmitt Trigger was similar to the B-H curve of soft magnetic core in shape, for this reason Schmitt trigger was used to construct fluxgate probe SPICE model. HSPICE was used in simulation. Simulation results shown that this model can simulate the real electrical properties of fluxgate probe accurately. This model can be used for fluxgate sensor interface integrated circuit research and fluxgate sensor application, and provide a reference to judge the performance for fluxgate sensors of which core parameters within a certain range.

Abstract:
Traditional fluxgate sensors used in geomagnetic field observations are large, costly, power-consuming and often limited in their use. Although the size of the micro-fluxgate sensors has been significantly reduced, their performance, including indicators such as accuracy and signal-to-noise, does not meet observational requirements. To address these problems, a new race-track type probe is designed based on a magnetic core made of a Co-based amorphous ribbon. The size of this single-component probe is only Φ10 mm × 30 mm. The signal processing circuit is also optimized. The whole size of the sensor integrated with probes and data acquisition module is Φ70 mm × 100 mm. Compared with traditional fluxgate and micro-fluxgate sensors, the designed sensor is compact and provides excellent performance equal to traditional fluxgate sensors with good linearity and RMS noise of less than 0.1 nT. From operational tests, the results are in good agreement with those from a standard fluxgate magnetometer. Being more suitable for modern dense deployment of geomagnetic observations, this small-size fluxgate sensor offers promising research applications at lower costs.

Abstract:
Fluxgate sensors are currently widely used for weak magnetic field measurement because of their relatively great performance, such as resolution, power consumption, and measurement of vector magnetic fields directly. Since the analog fluxgate sensor has some drawbacks, e.g., it would be influenced by the noise of the analog circuit. Hence, in recent years, the analog circuit is gradually inclined to be realized by digital processing in which the software parameter adjustment is employed to replace the analog components, which can greatly improve the flexibility of the design. This paper proposes a digital single-axis fluxgate sensor according to the cobalt-based amorphous effect. To be specific, the analog signal output by the fluxgate is sampled directly by an analog-to-digital converter to obtain the signal waveform in digital form after amplification. The demodulation, filtering, and integration of the signal are all solved by mathematical algorithms. Based on the working principle of the fluxgate sensor, the selection of the magnetic core material and coil winding method of the fluxgate sensor probe is introduced in detail. The design and function of the excitation circuit and preamplifier circuit, as well as the specific realization of digital signal processing, are described. Finally, the performance test of the digital fluxgate sensor was performed under laboratory conditions, and the magnetic anomaly detection comparison experiment was performed outdoors with commercial fluxgate sensors. To sum up, the linearity of the digital single-axis fluxgate sensor is better than 1 × 10−5, and the root mean square noise value is below 0.1 nT. At the same time, it has good magnetic field tracking performance and is extremely sensitive to the magnetic field of the measurement area.

Abstract:
Fluxgate magnetic sensors are especially important in detecting weak magnetic fields. The mechanism of a fluxgate magnetic sensor is based on Faraday’s law of electromagnetic induction. The structure of a fluxgate magnetic sensor mainly consists of excitation windings, core and sensing windings, similar to the structure of a transformer. To date, they have been applied to many fields such as geophysics and astro-observations, wearable electronic devices and non-destructive testing. In this review, we report the recent progress in both the basic research and applications of fluxgate magnetic sensors, especially in the past two years. Regarding the basic research, we focus on the progress in lowering the noise, better calibration methods and increasing the sensitivity. Concerning applications, we introduce recent work about fluxgate magnetometers on spacecraft, unmanned aerial vehicles, wearable electronic devices and defect detection in coiled tubing. Based on the above work, we hope that we can have a clearer prospect about the future research direction of fluxgate magnetic sensor.

Abstract:
Three-axis fluxgate sensors are quite widely used in various industries. However, due to the inherent limitations of their manufacturing process, various deviations can occur. In this paper, we study and analyze the sources of errors of three-axis fluxgate sensors, and construct a corresponding error model. The three-axis fluxgate sensor is successfully calibrated by the extended Kalman filter algorithm. Both simulations and experiments demonstrate that the method is effective in correcting the three-axis fluxgate sensor. In the experimental stage, the error was reduced by two orders of magnitude by applying the extended Kalman filter.

Abstract:
Fluxgate sensor has high sensitivity and temperature stability, small size and low power consumption. Fluxgate sensors can often provide very useful alternative in determining the location or position of a magnetic object, where other technologies cannot be used. For example, the GPR only, does not provide maximum results when used to characterize the magnetic material in the conductive subsurface or has a high reflectivity zone, but fluxgate sensors are capable. Characterization of magnetic materials in the soil subsurface is required. It is used as a proxy to determine the content of heavy metals and pollutants in the soil. In this work, we have carried out the development of fluxgate sensors for detection of magnetic material in soil subsurface. The fluxgate element consists of two pick-up coils, four excitation coils, and the ferromagnetic core. The highest sensitivity of fluxgate sensors that have been developed is 877 mV/µT and a maximum absolute error of 0.066 mV/µT. This paper will discuss the influence of the frequency of the primary magnetic field of the solenoid on the sensor response, the influence of soil magnetic susceptibility, and the effect of the presence of magnetic material in the soil subsurface to the sensor response.

This paper presents a complete set of SIMULINK models, which allow exhaustive behavioral simulations of fluxgate system to be performed. The model construction is detailed and it is applied to the Vacquier-type fluxgate sensor. Well known characteristics of these sensors are confirmed through the simulations. In spite of this simplicity, the model has been successfully used to describe the variation of the output of a Vacquier-type fluxgate sensor with the amplitude and the frequency of the driving current. Using a previously developed 2nd harmonic fluxgate magnetometer, some preliminary experimental results are obtained confirming the appearance at its output.

Abstract:
The paper considers non-destructive testing (NTDs) as a means to solve the flaw detection problems of magnetic products. It proposes a new probe-coil magnetic-field NDT, not requiring the pre-magnetization of the test object material, which is mandatory for all conventional magnetic flaw detection techniques. A new bifactor excitation of the fluxgate sensor’s sensitive element, based on double μ-transformation through the simultaneous activation of magnetic-modulating and electromagnetic-acoustic effects, is theoretically justified. The physical processes underlying the proposed technique are considered in detail, and a scheme for its practical implementation is described. The authors provide a variant of the new fluxgate’s original design, implementing the proposed excitation technique. The specifics of implementing the fluxgate operating modes are analyzed, testifying to the possibility of detecting a given class of flaws with the required coverage as well as ensuring the required diagnostic resolution during flaw detection, which, in fact, indicates a more reliable identification of both the flaw type and location. Herewith, the new fluxgate type features the advantages of improved functionality and lower cost due to its simple design. The paper also considers a method to experimentally study the capabilities of the proposed fluxgate sensor with a new bifactor excitation in detail. The results of the experimental study into its key specifications are provided, confirming its high resolution, narrower zone of uncertainty, and the possibility of detecting smaller flaws at greater depths compared to available analogs.

Abstract:
AbstractThe application area of fluxgate sensors is limited by their sensitivity. Medical researches create high demand on the magnetometers with the characteristics of high accuracy and sensibility for measuring weak magnetic fields produced by the human body, such as the heart‘s magnetic field. Due to the insufficient sensitivity of fluxgate sensors, superconducting magnetometers (SQUID) take the dominant position for the cardiomagnetic measurements. They have to be cooled by liquefied gases and it leads to high service costs. Therefore an idea of creating a high sensitive sensor based on fluxgate principles and known methods of measurement is attractive and up to date. This paper is dedicated to the modified flux-gate sensors based on Racetrack technology with a new approach of signal demodulation. The improved fluxgate sensor system provides detection of the heart‘s magnetic field without additional expenditures for use.

Abstract:
In recent years, the fluxgate sensor system has become increasingly important for the measurement of magnetic fields. It has become the instrument of choice for some aeronomy research programs, for ocean bottom deployment and for vessel detection by seafloor sensors. It has considerable potential for airborne magnetometry and gradient measurements. This renewed interest arises because the capabilities of the instrument are now known to be much superior to those achieved by earlier designs, and because there is a continued need for sensors with a vector capability. Added practical advantages accrue because it is a rugged instrument, economical to manufacture and has low power requirements. The advances in technology have not been accompanied by corresponding advances in the theoretical understanding of the fluxgate. Prior to publications from the University of British Columbia, most representations were cumbersome, incomplete and sometimes incorrect. The approach presented for the first time in this thesis introduces a gating function which straightforwardly represents the fluxgate mechanism separately from the complications of hysteresis and demagnetization. The characteristics of the gating function are easily measurable and can be regarded as the performance indices of the sensor. The approach also presents a general state equation which is valid not only for single sensors, but also for symmetric multiple sensors (e.g. gradiometers). Then the complete solution set (the monodromy, the general solution and periodic solution) is solved for the state equation. Based on the theories of Floquet-Lyapunov and of Hsu, the instability criterion and the method of calculation are investigated. The generalized instability map, illustrated in a parameter plane, is useful for the design of stable fluxgate sensor systems. The instability has been also checked in the phase space. The sensitivity map presented through this approach can be used to calculate the real signal for a fluxgate sensor with any value of parameters. Moreover, this approach not only formulates an integrated fluxgate theory, but also provides a guide to the selection of operating parameters and components for a practical design.<br>Science, Faculty of<br>Earth, Ocean and Atmospheric Sciences, Department of<br>Graduate

Abstract:
O presente trabalho trata da obtenção de ligas de NiFe de NiFeCo sob a forma de filmes finos e também no seu uso na tentativa em se construir um sensor magnético tipo fluxgate planar. A técnica de produção utilizada foi a eletrodeposição com regime galvanostático. A solução eletrolítica utilizada era constituída por sais de níquel e ferro e alguns aditivos. Para depositar os filmes de NiFe, o eletrodo auxiliar era constituído de níquel; enquanto que para depositar os filmes de NiFeCo, o eletrodo auxiliar era constituído de cobalto. Os filmes foram depositados em substratos de cobre utilizando densidades de corrente no intervalo de 4 até 28 mA/cm2, com tempos totais de 40 e 60 minutos. A caracterização morfológica foi realizada utilizando Microscopia Eletrônica de Varredura superficial e de seção lateral e para encontrarmos a composição dos elementos presentes na amostra, realizamos a Espectroscopia de Energia Dispersiva e Difração de Raios-X. Quanto à caracterização magnética foi utilizado o Magnetômetro de Amostra Vibrante e também magnetometria utilizando o Superconducting Quantum Interference Devices (este foi utilizado somente para os filmes de NiFeCo) como o elemento detector do equipamento. Os filmes de NiFe crescem com orientações cristalinas ao longo dos planos (110) e (200); as quantidades de níquel e ferro atingem valores constantes a partir da densidade de corrente de 15 mA/cm2 (embora sempre haja mais níquel que ferro); o ponto de menor coercividade magnética (58,4 A/m) também ocorre a partir dessa densidade de corrente, onde filmes com 1 ?m de espessura são conseguidos para um tempo total de 40 minutos. Nota-se uma assimetria para os campos aplicados perpendicular e paralelamente à superfície do filme. Os filmes de NiFeCo crescem com orientações ao longo dos planos (111) e (200). Embora sempre haja mais níquel (constante em 70%), as concentrações de Fe e Co se igualam apenas para uma densidade de corrente próxima de 15mA/cm2. Abaixo desse valor há mais ferro, e acima mais Co. A partir dessa densidade de corrente, novamente observa-se um mínimo no valor da coercividade magnética do material (81 A/m). A partir dessa densidade de corrente, tal grandeza teve seu valor mantido praticamente constante. Para essa densidade de corrente filmes de 6 ?m de espessura são obtidos para um tempo de 40 minutos. Uma menor assimetria magnética é observada comparada com o caso anterior. Por esses dados, acreditamos que o filmes de NiFeCo seja um melhor candidato para a confecção do sensor planar tipo fluxgate, e testes iniciais de sua fabricação também são apresentados.<br>This work presents the results about the fabrication and characterization of thin films of NiFe and NiFeCo alloys. The attempts to construct the planar fluxgate are also presented. Galvanostatic electrodeposition using an electrolytic solution containing Ni and Fe was used: NiSO4 (0,7 mol/l); NiCl2 (0,02 mol/l); FeSO4 (0,03 mol/l); H3BO3 (0,4 mol/l) and C7H5O3NS.2H2O (0,016 mol/l). The auxiliary electrode was made on Ni for the NiFe films, while another one made on Co was used for the NiFeCo films. Films were deposited on copper substrates using current densities form 4 up to 28 mA/cm2, and total deposition time of 40 and 60 minutes. Structural characterization was performed using Scanning Electron Microscopy (surface and cross-section); Energy Dispersive Spectroscopy, and Xray Diffraction. Magnetic characterization was performed using two methods: the Vibrating Sample Magnetometry and magnetometry using a SQUID (Superconducting Quantum Interference Devices) sensor. NiFe films grow with crystalline planes oriented along the (110) e (200) directions; the amount of each material reach constant values for current densities above 15 mA/cm2 (even though there is always more Ni). The point of minimum magnetic coercivity (58,4 A/m) also occurs for this current density, where films 1 ?m-thick are obtained for a total deposition time of 40 minutes. An asymmetry is observed for magnetic fields applied parallel and perpendicular to the surface of the films. NiFeCo films grow with crystalline planes oriented along the (111) and (200) directions; the amount of Ni remains constant (about 70%) for the whole current density range. The amount of Fe decreases with increasing current density, while the amout of Co shows the opposite behavior. They have equal values for current densities of about 15mA/cm2, where the minimum coercivity of 81A/m is achieved. For higher current densities the coercivity remains constant. For the current density of 15mA/cm2, 6 ?m-thick films are obtained for a total deposition time of 40 minutes. The magnetic asymmetry is smaller than for the case of the NiFe films. According to the obtained data, we believe that NiFeCo is a better candidate for the fabrication of planar magnetic fluxgate sensors. Initial tests for the fabrication of a prototype are also presented.

Abstract:
This thesis describes the optimization and characterisation of an integrated fluxgate sensor. It is fabricated with a CMOS-compatible technology for planar coils with ferromagnetic cores. Limitations of sensor measurement range and linearity are analyzed by analytical and numerical calculations of stray fields and demagnetizing effects in the cores coupled with signal analysis of the calculated coil output voltage. The sensor resultion is limited by magnetic domain effects. Based on these results the sensor layout is optimized for the compass application. Electrical and magneto-optical methods for on wafer characterisation of the ferromagnetic layer, the electrical and magnetical coil parameters and the sensor itself are developed and meet production requirements.

Fluxgate magnetometers have always been of interest to the technical and scientific communities as practical and convenient sensors for vector magnetic field measurements in the range of microtesla requiring a resolution of hundreds of picotesla at room temperature, and they find applicability in fields such as space, geophysical exploration and mapping, non destructive testing, as well as assorted military applications. In this Thesis the research work on RTD Fluxgate is presented along with the development of models, prototypes and their characterization. Classical but also new technological approaches to realise low-cost Fluxgate magnetometers are proposed.

Noise sources in a Schonstedt spinner magnetometer, the primary laboratory instrument used in paleomagnetic research, and various methods for dealing with them are investigated theoretically and experimentally. Based on the results, an instrument is designed and constructed which replaces the Schonstedt sensor and magnetometer with the recently developed University of British Columbia ring core sensor and magnetometer, and the Schonstedt analyzer with an adaptive filter. A 10dB improvement in the signal to noise ratio was achieved in the magnetometer, and a superior method for measuring this signal, using software, is suggested.

Abstract:
Magnetometers are sensors that measure the magnitude and direction of a magnetic field. There are many types of magnetometers available, but they all rely on electromagnetic principles to measure fields. The most common types are Hall effect, anisotropic magneto-resistive (AMR) and fluxgate sensors. The goal of this study is to investigate several magnetometers to evaluate their capability to detect small changes in an ambient field. These small changes are on the order of 10 milligauss (1 �T) and are caused by the inverse-magnetostrictive effect, or Villari effect, from ferromagnetic pipes. The chosen magnetometer must have a low noise signal and a fine resolution to properly measure the field from the inverse-magnetostrictive effect. To evaluate the chosen magnetometers, multiple sets of measurements were made in a stationary magnetic field and the standard deviation of the data sets were calculated. The noise of some sensors was further investigated to verify that it was normally distributed.

Abstract:
Integrity assessment of pipelines is vital to ensure that oil and gas pipes have adequate strength to prevent leaks and ruptures. Regular inspections are conducted to confirm safe operation conditions of pipelines. The industry's principle method for assessing pipelines is in-line inspection (ILI), involving the passing of a device along the inside of a pipe to assess the condition of the pipeline. ILI devices can be fitted with a number of sensors allowing various measurement parameters to be obtained simultaneously. Not all pipelines are suited to ILI for reasons such as small diameter, obstructions within the pipe, or insufficient access to deploy or retrieve the ILI tools. These pipelines are sometimes referred to as 'difficult to inspect'. Alternative methods for examining pipeline condition are required, with a range of technologies collectively known as Large Standoff Magnetometry (LSM) offering a promising solution for detection of pipe defects from a distance, reducing the need for excavation. LSM utilises the coupling between defects and changes in the magnetic properties of the pipeline material as a method for evaluation of pipe walls to identify the location of areas that require repair or further monitoring. Trials of existing commercial instruments by the pipeline industry have shown sufficient promise to investigate the technologies further. However, vendors have supplied limited information on the underpinning physics of both the materials being tested and the instrument technology. The purpose of the project is to establish the ability of LSM to detect corrosion in API 5L pipe grades B to X70. The aim of Work Package 02 is to review the physics of the agreed pipeline defects and fluxgate type magnetic sensors. The properties of pipeline-specific soft magnetic materials are investigated to understand corrosion, how this alters the material properties and how this can affect the associated magnetic fields surrounding the material. The physics of fluxgate magnetometers and gradiometers are also reviewed to assess the ability of LSM to detect these two features.
