Abstract:

Imagine if your biggest health problem could be solved with the flip of a switch. Deep-brain stimulation (DBS) offers such a dramatic recovery for a range of neurological illnesses, including Parkinson's disease, epilepsy and major depression. Yet the metal electrodes implanted in the brain are too bulky to tap into intricate neural circuitry with precision and corrode in contact with tissue, so their performance degrades over time. Now neurophysiologists have developed a method of DBS that avoids these problems by using microscopic magnets to stimulate neurons. When you are citing the documen

Abstract:

We present the development of a far-field magneto-optical Kerr effect microscope. An inverted optical microscope was constructed to accommodate Kerr imaging and atomic force microscopy. In Kerr microscopy, magnetic structure is investigated by measuring the polarization rotation of light reflected from a sample in the presence of a magnetic field. Atomic force microscopy makes use of a probe which is scanned over a sample surface to map the topography. The design was created virtually in SolidWorks, a three-dimensional computer-aided drafting environment, to ensure compatibility and function o

Abstract:

In this thesis, two selected topics in magnetism are studied using theoretical modelling and computational methods. The first of these is the magnetocrystalline anisotropy energy (MAE) of transition metal based magnets. In particular, ways of finding 3d transition metal based materials with large MAE are considered. This is motivated by the need for new permanent magnet materials, not containing rare-earth elements, but is also of interest for other technological applications, where the MAE is a key quantity. The mechanisms of the MAE in the relevant materials are reviewed and approaches to in

Abstract:

Rare earth permanent magnets have been broadly integrated into various applications, such as advanced electric motor technologies which partly relieve the current energy crisis worldwide by taking advantages of their extraordinary magnetic properties. Traditional approaches for increasing the intrinsic coercivity (Hci) of rare earth permanent magnets typically come at the expense of remanence, resulting in a reduction of maximum magnetic energy product [(BH)max]. Therefore, novel design and processing strategies are in urgent need to circumvent this trade-off in the advanced rare earth permane

Magneto-sensitive elastomers (MSEs) establish a special class of smart materials, which are able to change their shape and mechanical behavior under external magnetic field. Nowadays, MSEs are one of the most perspective smart materials, since they can be used for design of functionally integrated lightweight structures in sensors, robotics, actuators and damper applications. MSEs typically consist of micron-sized magnetizable particles (e.g. carbonyl iron) dispersed within a non-magnetic elastomeric matrix.

Abstract:

Initially, the switching behaviours of single layer NiFe rings are investigated. It is demonstrated that their magnetic switching is a competition between local energy barriers and the total energy of the rings’ magnetic states. In 5<i>μ</i>m diameter NiFe rings the vortex state formed during magnetic switching alternates stochastically from one field cycle to the next. Micromagnetic simulations are used to demonstrate that this behaviour is caused by the thermal excitation of a nanoscopic region of edge spins which have a disproportionate effect on the switching of the ring as a whole.

However, analytical expressions for the diffusion spectrum of particles only exist for simple geometries such as cylinders, which are often used as a model for intra-axonal d

The goal of this thesis is to employ target-specific MR contrast agents to regionally alter relaxation rates, resulting in increased contrast in ex vivo MRM of the human brain, with the aim of providing richer information about cyto- and/or myelo-archit

Abstract:

Thesis advisor: Michael J. Naughton<br>Magnetic resonance force microscope (MRFM) is a relatively new form of microscopy, which provides very high-resolution images in three dimensions (3D). Further development of this microscope would provide a great instrument that would further many areas of research, including physics, material science, and biology. This research project aims to explore the possibilities of making a MRFM more sensitive by using carbon nanotubes or zinc oxide nanowires as cantilevers, making the resolution much higher and the scans accurate to a much smaller scale.
