Abstract:

The results of experimental and theoretical studies of the influence of the current value on the characteristics of anisotropic magnetoresistive magnetic field sensors based on FeNiCo alloy with a "barber-polе" structure are presented. A significant difference was found between the volt-oersted characteristics of the forward and reverse strokes with an increase in the intrinsic current caused by the input supply voltage at sufficiently high external magnetic fields. A theoretical calculation of the volt-oersted characteristic was carried out within the framework of the model of one-dimensional heterogeneity of the magnetization distribution, which coincides with the experimental curves of the forward path.

Abstract:

The current-driven magnetization precession dynamics stimulated by Spin-Transfer Torque (STT) in a trilayer spin-valve device (typically Spin-Torque Nanooscillator (STNO)) is numerically investigated by solving the Landau–Lifshitz–Gilbert–Slonczewski (LLGS) equation. We have devised four STNO devices made of ferromagnetic alloys such as CoPt, CoFeB, Fe[Formula: see text]B[Formula: see text]Ni2 and EuO, which act as free and fixed layers. Here, copper acts as a nonmagnetic spacer for all the devices. In this work, we have introduced the current-induced Oersted field, which is generated when a spin-polarized current passes through the device. The generated Oersted field strength is varied by increasing the diameter of the STNO device. Frequency tunability is achieved in all the four devices, whereas the power of the individual device reduces. The frequency and power of the devices depend entirely on the saturation magnetization of the material, which inherently reflects in the current density and the coherence of the spin-polarized DC. In all devices, the frequency increases, whereas the power decreases by increasing the strength of the Oersted field. Among the four devices, the maximum frequency can be tuned up to 104[Formula: see text]GHz with 40[Formula: see text]nm device diameter, which is obtained for EuO material. This opens a promising source and paves a glittering future for the nanoscale spintronic devices.

Abstract:

A methodology to fabricate ultrasoft CoFe nano-/microfilms directly via electrodeposition from a semineutral iron sulfate solution is demonstrated. Using boron-reducer as the additive, the CoFe films become very soft with high magnetic moment. Typically, the film coercivity in the easy and hard axes is 6.5 and 2.5 Oersted, respectively, with a saturation polarization up to an average of 2.45 Tesla. Despite the softness, these shining and smooth films still display a high-anisotropic field of ~45 Oersted with permeability up to 104. This kind of films can potentially be used in current and future magnetic recording systems as well as microelectronic and biotechnological devices.

Abstract:

The magnetoresistance (MR) of a material is typically insensitive to reversing the applied field direction and varies quadratically with magnetic field in the low-field limit. Quantum effects, unusual topological band structures, and inhomogeneities that lead to wandering current paths can induce a cross-over from quadratic to linear MR with increasing magnetic field. Here we explore a series of metallic charge- and spin-density-wave systems that exhibit extremely large positive linear MR. By contrast to other linear MR mechanisms, this effect remains robust down to miniscule magnetic fields of tens of Oersted at low temperature. We frame an explanation of this phenomenon in a semiclassical narrative for a broad category of materials with partially gapped Fermi surfaces due to density waves.

Abstract:

Abstract. We perform a case study of a favorable conjunction of an overpass of the Oersted satellite with the field-of-view of the SuperDARN Syowa East radar during an interval of the southward IMF Bz. At the time, the radar observed an L-shell aligned boundary in the spectral width around the dayside ionosphere. Simultaneously, high-frequency (0.2–5Hz) magnetic field fluctuations were observed by the Oersted satellite's high-time resolution magnetometer. These magnetic field fluctuations are considered to be Alfvén waves possibly associated with the particle which precipitates into the dayside high-latitude ionosphere when magnetic reconnection occurs. It has been theoretically predicted that the time-varying electric field is the dominant physical process to expand the broad HF radar Doppler spectra. Our observation clearly demonstrates that the boundary between narrow and broad spectral widths is corresponding well to the boundary in the level of the fluctuations, which supports the previous theoretical prediction. A close relationship between electric and magnetic field fluctuations and particle precipitations during southward IMF conditions has been confirmed by many authors. The present observation allows us to suggest that the boundary between narrow and broad Doppler spectral widths observed in the dayside ionosphere is connected with the signature of the open/closed field line boundary, such as the cusp particle precipitations via electric and magnetic field fluctuations for the case of the negative IMF Bz conditions.

Abstract:

We have studied effect of current annealing on domain wall dynamics of FeCoMoB microwires. It was showed that 10 minutes of current annealing corresponds to 1 hour of classical annealing in furnace. Moreover, electrical current flowing through microwire produces Oersted magnetic field and therefore circular magnetic anisotropy is induced during annealing. As a result, induced circular magnetic anisotropy prefers vortex domain wall with velocities up to 3 km/s that can be observed in the current annealed nanocrystalline FeCoMoB microwires with much higher temperature stability.

Abstract:

Static magnetic solitons in a thin film such as skyrmions are metastable states that can be stabilized through a balance of the exchange interaction and various relativistic interactions. One of the most effective stabilizing terms is the antisymmetric exchange along with others such as magnetostatic interactions in confined structures, as well as a current-carrying nanocontact on a thin ferromagnetic film. In this article, the effect of a nanocontact current on the energies of both topological (T-type) and nontopological (NT-type) solitons has been investigated. Without an antisymmetric exchange interaction, the Oersted field from a nanocontact can stabilize both soliton types with the NT soliton as the ground state. With the antisymmetric exchange, there is a critical nanocontact current, where the T soliton becomes the ground state.

The dependence of free layer coercivity on the angle between easy axis and applied magnetic field was studied on [Ta, (Ni80Fe20)60Cr40]/ Ni80Fe20/Co90Fe10/Cu/Co90Fe10/Mn75Ir25/Ta spin valves with various interlayer coupling. Sharp decrease on the angle was observed for ferromagnetically coupled spin valves. The coercivity was reduced down to tenth of Oersted without any decrease of GMR-effect by forming nearly parallel anisotropy configuration. The angles at which the transition from hysteretic to anhysteretic magnetic reversal takes place are detected by analyses of the angle dependence of coercivity. Interpretation of experimental data is based on Stoner-Wohlfarth coherent rotation approach.

Abstract:

In this paper, patterned nanoscale magnetic tunnel junctions (MTJs) with different geometrical structures, including nanodisk (ND), nanoellipse (NE), nanoring (NR) and nanoelliptical ring (NER) with the scale of around 100nm and ring width of around 30nm, were fabricated, respectively. The geometrical-shape dependence of magnetic field-driven and current-induced magnetization switching (CIMS) were studied in the nanoscale magnetic tunnel junctions (MTJs). The NER-MTJs showed robust magnetization switching and low critical current density of CIMS, comparing with other geometrical-shaped MTJs. This may be due to the different distribution of current-induced Oersted field in different geometrical structures, which plays an assisted role in CIMS. The present experiments indicate that NER-MTJs may be one of the promising candidates for the cells of high-density and low-consumption spintronic devices.

Abstract:

Abstract. Recently, a model of large-scale, field-aligned current (FAC) structures, based on zero-frequency MHD surface wave (SW) modes that can emerge from the solar wind-Earth's magnetosphere interaction, has been proposed. The FAC polarity and intensity distribution are quantified as a function of the solar wind parameters and the interplanetary magnetic field (IMF) magnitude that enter as input parameters. Besides, there are input parameters intrinsic to the Earth's magnetosphere – the size of the polar cap and the boundary regions and their plasma density variations. Influence of the IMF By component on the FAC structure is examined here. Depending on the IMF By magnitude, the predicted six-cell FAC structure tends to evolve in a spiral-like fashion. This large-scale FAC model is compared with experimental evidences and empirical FAC models based on DE-2 satellite data and high-precision Oersted and Magsat satellite magnetometer data. Among the various achievements of these long-term satellite measurements, an observation/discovery of a ground-based state of FACs which includes a pair of large-scale FACs in the polar cap under both positive and negative IMF Bz has been pointed out. The FAC pattern is qualitatively and quantitatively consistent with experimental data for both polar cap FAC and Region 1 and Region 2 FAC systems.

Abstract:

We present a study of magnetic structures with controllable effective exchange energy for Josephson switches and memory applications. As a basis for a weak link we propose to use a periodic structure composed of ferromagnetic (F) layers spaced by thin superconductors (s). Our calculations based on the Usadel equations show that switching from parallel (P) to antiparallel (AP) alignment of neighboring F layers can lead to a significant enhancement of the critical current through the junction. To control the magnetic alignment we propose to use a periodic system whose unit cell is a pseudo spin valve of structure F1/s/F2/s where F1 and F2 are two magnetic layers having different coercive fields. In order to check the feasibility of controllable switching between AP and P states through the whole periodic structure, we prepared a superlattice [Co(1.5 nm)/Nb(8 nm)/Co(2.5 nm)/Nb(8 nm)]6 between two superconducting layers of Nb(25 nm). Neutron scattering and magnetometry data showed that parallel and antiparallel alignment can be controlled with a magnetic field of only several tens of Oersted.

Abstract:

Magneto-optic surface plasmon resonance (MOSPR)-based sensors are highly attractive as next-generation biosensors. However, these sensors suffer from oxidation leading to degradation of performance, reproducibility of the sensor surface, because of the difficulty of removing adsorbed materials, and degradation of the sensor surface during surface cleaning and these limit their applications. In this paper, I propose MOSPR-based biosensors with 0 to 15 nm thick inert polycarbonate laminate plastic as a protective layer and theoretically demonstrate the practicability of my approach in water-medium for three different probing samples: ethanol, propanol, and pentanol. I also investigate microstructure and magnetic properties. The chemical composition and layered information of the sensor are investigated using X-ray reflectivity and X-ray diffraction analyses and these show distinct face-centered-cubic (fcc)-Au (111) phases, as dominated by the higher density of conduction electrons in Au as compared to Co. The magnetic characterization measured with the in-plane magnetic field to the sensor surface for both the as-deposited and annealed multilayers showed isotropic easy axis magnetization parallel to the multilayer interface at a saturating magnetic field of <100 Oersted (Oe). The sensor showed a maximum sensitivity of 5.5 × 104%/RIU (refractive index unit) for water–ethanol media and the highest detection level of 2.5 × 10−6 for water-pentanol media as the protective layer is increased from 0 to 15 nm.

Abstract:

The Maxwell’s vicious electromagnetic concept which can also be defined as electric magnetism occurred as a result of superficial and, exclusively, erroneous impression of the Great Theorist on the famous Oersted Experience. The fateful concept for physical science: “electrons moving in a conductor are direct sources of a magnetic field”, was put forward by Maxwell in the absence of knowledge of real physical processes occurring in a conductor with an electric current. Paradoxical as it may see but this vicious concept, again thanks to the outward impression, has been accepted by the world physical community and dominates in physical science for almost 150 years, as an absolute truth. As the result the true sources of the magnetic field - real magnetic poles (magnetic charges) which are the structural components of atoms and substance, were “buried alive”. It is Maxwell’s vicious electric magnetism that suppressed the interest of scientists in the search for and detection of real magnetic charges in atoms and substance and pushed of the physical theory into the “swamp” of relativism. The author’s experimental and theoretical studies have shown that a main reason for ignoring magnetic charges and, and therefore, the emergence of a vicious concept of electric magnetism, is the radically different physics of the confinement of electrons and magnetic charges in the structures of Physical mass (in atoms, nucleons, substance and others).

Abstract:

The concept of the electric magnetism Maxwell (1873) is a result of the superficial and exceptionally erroneous impression of Great Physicist from the well-known experience of Oersted. However the world scientific community adopted this erroneous impression as the ultimate truth and, following Maxwell, declared the moving electric charges to be direct sources of the magnetic field. At same time, the true sources of the magnetic field the magnetic poles (magnetic charges) which are the real structural components of atoms and substance, were “buried alive”. Such theoretical discoveries as the curvature of four-dimensional space-time, explaining the physics of gravity, the big bang, the journey through “Black holes” in space and time, and many others, are well known. All these discoveries were formed without taking into account the existence of real magnetic poles (magnetic charges) since were based on the provisions of Maxwell’s flawed electromagnetic concept. The main reason which for more than 100 years inhibits the detection and recognition of real magnetic charges, are the special conditions of their confinement in a substance that are radically in the substance different from confinement of electrons. The results the experiments of F. Ehrenhaft, the present author and others in which of real magnetic charges were observed in the structures of atoms and substance prove that the existing concept of electric magnetism is deeply erroneous, and the fundamental change in physical priorities is the most important task today. Physical science, freed from vicious EM-concept of Maxwell and the accompanying relativism will offer humanity innovations in the form of practically useful physical effects and manifestations. This article presents 11 such innovations discovered by the author when embedded into the representations of real magnetic charges including, example, the electromagnetic (vortex) nature of the gravitational field, as well as the effects of Gravitational levitation and Intra-atomic gravitational shielding (IAGS). The first effect allows, for example, a person to go out into space without the use of jet thrust. The IAGS effect largely determines the physics of such fundamental manifestations as the chemical bonding, nuclear forces, and radioactivity.

Abstract:

We report on experimental studies focusing on the dynamic ac magnetic susceptibility of a ferronematic. It has been shown recently, that in the isotropic phase of a ferronematic, a weak dc bias magnetic field of a few oersteds increases the ac magnetic susceptibility. This increment vanishes irreversibly if the substance is cooled down to the nematic phase, but can be reinduced by applying the dc bias field again in the isotropic phase [Tomašovičová, N. et al. Soft Matter 2016, 12, 5780–5786]. The effect has no analogue in the neat host liquid crystal. Here, we demonstrate that by doubling the concentration of the magnetic nanoparticles, the range of the dc bias magnetic field to which the ferronematic is sensitive without saturation can be increased by about two orders of magnitude. This finding paves a way to application possibilities, such as low magnetic field sensors, or basic logical elements for information storage.

Abstract:

The frequency of sublethal damage was examined in two ophiuroid species, Palaeocoma milleri and ?Ophioderma tenuibrachiata (Ophiodermatidae), from a shallow-water Jurassic “starfish bed.” None of 60 specimens was regenerating arms, a result that agrees with four previous studies of Paleozoic and early Mesozoic ophiuroids. By contrast, 66.1 percent of a living Ophioderma brevispinum population from Belize were regenerating one or more arms. For living populations of Ophiothrix oerstedi, the natural injury frequency was high at sites where the field mortality of tethered individuals was high. All predators that have been observed feeding on ophiuroids cause sublethal injuries, which would appear as regenerating arms in the fossil record. These results support the hypothesis that predation pressure on ancient ophiuroid populations was low and increased after the Jurassic.

Abstract:

1. Ocular tracking in two species of stomatopod crustaceans, Squilla empusa (Say) and Gonodactylus oerstedii (Hansen), was studied by presenting animals with small targets moving to their right and left. 2. Squilla empusa showed no indication of ocular movement responses synchronized with the target's motion, whereas Gonodactylus oerstedii often tracked the target through large angular amplitudes. 3. The region of visual fixation in G. oerstedii is probably the ommatidial patches in line with the eyecup axis. This is suggested by the arrangement of ommatidial axes on the eye's circumference, and by the alignment of the eyes and the rotational motions they make as they observe an approaching target. 4. Tracking is irregular, probably because the animal pays attention to the target only intermittently. Targets are most stimulatory as they move nearly in front of an animal. Eye tracking responses become larger, more frequent and more accurate with increasingly anterior target positions. 5. During visual tracking, the eyes perform both smooth and saccadic tracking movements. Eye movements in the size range 7.5°–15° are made to near the position of the target at movement onset, but are less accurate relative to the target's position at the end of the movement. 6. During visual tracking, the two eyes apparently act with complete independence. Movements of one eye are uncorrelated with movements of the other, both for extreme and central locations of the moving target. 7. The existence of ocular independence during smooth pursuit and saccadic tracking in G. oerstedii may be possible because of the redundancy of visual fields existing in each eye, which could permit monocular measurements of distance to a viewed object. If so, each eye is capable of providing a complete description of the location of a target in space.
