Tailoring of magnetic softness and GMI effect in Fe-rich thin magnetic wires

AIP Advances, 2018
We present comparative studies of magnetic properties and giant magnetoimpedance (GMI) effect of Fe and Co-rich microwires. As-prepared Co-rich microwires present much higher GMI ratio.

Development of Co-rich glass-coated microwires with high GMI effect

AIP Advances
We studied the Giant Magneto-Impedance (GMI) effect and magnetic properties of Co72Fe4B13Si11 glass-coated magnetic microwires with two different diameters. Substantially different frequency dependence of GMI effect is observed in studied microwires.

Stress-Induced Magnetic Anisotropy Enabling Engineering of Magnetic Softness and GMI Effect of Amorphous Microwires

Applied Sciences, 2020
Stress-annealing enabled a considerable improvement in the GMI effect in both Fe- and Co-rich glass-coated microwires. Additionally, a remarkable magnetic softening can be achieved in stress-annealed Fe-rich microwires.

Computational modeling of GMI effect in Co-based amorphous ribbons [PDF]

Journal of Inequalities and Applications, 2013
The author claims to use a self-organizing feature map neural network (SOFM) to model GMI effects in Co-based amorphous ribbons and she even describes the already classical SOFM training algorithm. However, as in her paper [J. Inequal. Appl. 2013, Article ID 216, 4 p.

Amorphous microwires with enhanced magnetic softness and GMI characteristics

EPJ Web of Conferences, 2012
In this paper we present results on correlation of GMI effect and soft magnetic behavior in Co-rich microwires with low magnetostriction constant. Correlation between magnetoelastic anisotropy and magnetic field dependences of diagonal and off-diagonal ...

Estimation of the frequency and magnetic field dependence of the skin depth in Co-rich magnetic microwires from GMI experiments

Journal of Science: Advanced Materials and Devices, 2016
We studied giant magnetoimpedance (GMI) effect in magnetically soft amorphous Co-rich microwires in the extended frequency range. From obtained experimentally dependences of the GMI ratio on magnetic field at different frequencies we estimated the ...

Hysteresis in Asymmetrical GMI Effect in Amorphous Microwires

Acta Physica Polonica A, 2014
The double-peak behaviour of giant magneto-impedance (GMI) dependence on the external magnetic field strength H is observed in as-cast glass-covered amorphous thin wire $Co_{70.5}Fe_{4.5}Si_{15}B_{10}$ (microwire), as well as in microwire with the ...

Optimization of the high-frequency magnetoimpedance response in melt-extracted Co-rich microwires through novel multiple-step Joule heating

Journal of Science: Advanced Materials and Devices, 2021
The optimization of the high frequency giant magnetoimpedance (GMI) effect and its magnetic field sensitivity in melt-extracted Co69.25Fe4.25Si13B12.5Nb1 amorphous microwires was systematically studied through a multi-step Joule annealing (MSA) technique.
