Conventional Hall devices are widely employed to measure magnetic fields produced by millimetre sized (or larger) current-caring conductors or permanent magnets with a standard active area of about (100 um)^2. Micro-Hall sensors have recently emerged as a ...
Here we introduce a novel neutron imaging method, which is based on the effect that the spatial coherence of the neutron wave front can be changed through small-angle scattering of neutrons at magnetic domain walls in the specimen. We show that the techniq ...
The present thesis report deals about the material scientists contribution to the interdisciplinary European project "MAGNANOMED" involving people having very different backgrounds (physicist, chemists, biochemists, veterinary surgeons, ...). The work carr ...
Magnetic zigzag edges of graphene are considered as a basis for novel spintronics devices despite the fact that no true long-range magnetic order is possible in one dimension. We study the transverse and longitudinal fluctuations of magnetic moments at zig ...
Excitation circuit is formed by a single planar coil of an essentially square shape (9) with the magnetic core (10) in the f of a diagonal cross with the legs (101, 102) extending towards the corners of the square defined by the outer circumference (90) th ...
Using a generalized anisotropic tokamak equilibrium and an exact guiding centre drift formulation, the effect of parallel and perpendicular anisotropy on the toroidal precession drift is investigated. Significant differences between parallel and perpendicul ...
We have used the finite element method to study the extraordinary magnetoresistance (EMR) effect of semiconductor-metal hybrid structures in rectangular device geometries. These have recently been found to exhibit intriguing properties interesting for magn ...
We have patterned multilayers of amorphous magnetic foils of Metglas/sup /spl reg// 2714a (cobalt-based) and Cu foil into microstructures of different sizes. We have studied the GM effect in these structures, and we have characterized the behavior of the r ...
This paper presents results from numerical modelling of BSCCO conductors performed with finite element method software. The AC losses are calculated and compared for conductors of different geometry and aspect ratio – an elliptical tape with anisotropic Jc ...
A new compact 2D planar fluxgate sensor using a ferromagnetic amorphous metal core is described. The fluxgate sensor consists of two orthogonal planar metallic coils and a ring shaped amorphous magnetic ribbon mounted on a PCB substrate. Each planar coil i ...
