Tuning of Magnetic Properties of Magnetic Microwires

IEEE Magnetics Letters, 2018
Techniques for fine tuning the magnetic properties of glass-covered amorphous microwires are discussed. They include selection of nominal components and geometric proportions, conditions for thermal treatment, and application of mechanical stress and crossed magnetic fields.

Magnetic Properties of Nanocrystalline Microwires

Journal of Electronic Materials, 2015
We have studied magnetic properties of Finemet-type and Hitperm-type microwires. In the case of the Finemet-type we observed that GMI effect and magnetic softness of microwires can be considerably improved by annealing. A considerable GMI effect has been observed in annealed FeCuNbSiB microwires exhibiting nanocrystalline structure. From the dependence

Controlling the domain wall dynamics in Fe-, Ni- and Co-based magnetic microwires [PDF]

Journal of Alloys and Compounds, 2020
We studied influence of post-processing (annealing and stress-annealing) on domain wall dynamics in Fe-, Ni- and Co- based magnetic microwires with spontaneous and induced magnetic bistability.

Magnetization switching in ferromagnetic microwires

Physical Review B, 2010
Magnetization states of amorphous soft ferromagnetic microwires are studied by experiment and theoretically. It is shown that in low applied axial fields, on increasing the circular magnetic field produced by current, the initial homogeneous circular magnetization distribution evolves in three sequential steps: (i) the appearance of a helical ...

Fast magnetic domain wall in magnetic microwires

Physical Review B, 2006
The propagation of domain walls in magnetic microwires has been investigated over the temperature range $77\text{--}373\phantom{\rule{0.3em}{0ex}}\mathrm{K}$. Very high domain wall velocities, up to $1800\phantom{\rule{0.3em}{0ex}}\mathrm{m}∕\mathrm{s}$, were observed, in combination with enhanced domain wall mobilities at high temperature. In contrast,

Magnetic-flux-induced conductance steps in microwires

Physical Review B, 1993
We predict a new type of steplike fluctuations in the magnetoconductance of three-dimensional ballistic microwires. These mesoscopic fluctuations, which appear on a scale corresponding to a small fraction of the quantum unit of magnetic flux ${\mathrm{\ensuremath{\Phi}}}_{0}$=hc/e, are a novel manifestation of the Aharonov-Bohm effect.

Manipulation of Magnetic Domain Structures With Helical Magnetization in Magnetic Microwires

IEEE Transactions on Magnetics, 2014
We report investigations on crossed magnetic field-induced transformation of surface domain structure in amorphous glass covered microwires. The study has been performed by a magneto-optical Kerr effect technique using optical microscopy. The existence of elliptic domain structure has been demonstrated experimentally.

Magnetostriction in glass-coated magnetic microwires

Journal of Magnetism and Magnetic Materials, 2003
Abstract The hysteretic magnetic properties of glass coated magnetic microwires depend on the magnetostriction constant: Co-rich microwires with negative magnetostriction constant present an almost non-hysteretic loop with relatively high magnetic anisotropy field up to around 8 kA/m.

Tunable Magnetic Anisotropy and Magnetization Reversal in Microwires

2017
Surface magnetization reversal of Co-rich and Fe-rich amorphous glass covered microwires in the presence of torsion mechanical stress has been studied by magneto-optical Kerr effect. The dependence of the angle of the helical anisotropy on the applied torsion stress has been obtained based on the analysis of the magneto-optical experimental results ...

Evaluation of use of magnetically bistable microwires for magnetic labels

physica status solidi (a), 2010
AbstractThe dynamics of the magnetization reversal by means of head‐to‐head domain‐wall propagation is investigated both experimentally and theoretically for magnetic labels made from Fe‐rich bistable glass‐coated microwires. It is shown that the amplitudes of the electromagnetic harmonics generated by bistable Fe‐rich magnetic labels of the length 1–4
