Numerical modelling of GMI effect in soft magnetic amorphous ribbons
Journal of Magnetism and Magnetic Materials, 2004A numerical simulation model based on Machado et al. [J. Appl. Phys. 79 (1996) 6558] was developed to study the relaxation time and GMI in a series of Co-and Fe-based commercial alloys in the ribbon form as a function of excitation frequency and DC bias field. In Machado et al's model the relaxation time was considered as constant.

Tailoring of Magnetic Properties and GMI Effect of Amorphous Microwires by Annealing
2015We studied Giant magnetoimpedance (GMI) effect and magnetic properties of amorphous Fe-Co rich as-prepared and annealed microwires. We measured the GMI magnetic field and frequency dependences, hysteresis loops and domain walls (DWs) dynamics of composite microwires produced by the Taylor-Ulitovski technique.

Effect of Annealing on Off-Diagonal GMI Effect of Co-Rich Amorphous Microwires
IEEE Transactions on Magnetics, 2014We studied giant magnetoimpedance (GMI) effect and magnetic properties of Co 69.2 Fe 4.1 B 11.8 Si 13.8 C 1.1 amorphous as-prepared and annealed microwires. We observed that these properties can be tuned by heat treatment. High GMI effect has been observed in as-prepared Co-rich microwires.

The influence of the composition on the GMI effect in low magnetostrictive amorphous microwires
Journal of Magnetism and Magnetic Materials, 2004Abstract The influence of the composition on both the magnetostriction and the GMI effect in Co 72.5− x Fe x Si 12.5 B 15 ( x =5.5–6.2) amorphous glass-covered wires is investigated. The basic magnetic properties of these materials as well as internal stresses induced by the glass cover during the preparation process strongly influence the GMI ...

A method to generate high-frequency magnetic field for GMI effects
2010 International Conference on Microwave and Millimeter Wave Technology, 2010In order to make an in-depth study on high-frequency characteristics of GMI effect, this article presents a practical method to generate the alternating magnetic field. Comparing three feasible ways, the microstrip line is the optimum selection. Based on equivalent analysis method and CST software simulation, the distributing of microstrip line ...

Simulation of stress effect on GMI in soft magnetic amorphous film
2017 IEEE International Magnetics Conference (INTERMAG), 2017Soft magnetic amorphous film not only has the giant magneto-impedance (GMI) effect, but also significantly affected by stress-induced magnetic anisotropy[1].
