Optimization of Giant Magnetoimpedance Effect in Fe-rich Microwires

2018 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2018
We observed remarkable optimization of the magnetic softness in Fe-rich magnetic microwires by stress-annealing. It is found that the as-prepared Fe-rich microwires present rectangular hysteresis loops. The magnetic softness and magnetoimpedance effect of the Fe-rich microwires can be considerably improved by annealing.

Giant magnetoimpedance effect in Fe–Nb–B ribbon

Solid State Communications, 1999
Abstract In the present paper we report first evidence of a giant magnetoimpedance effect in Fe–Nb–B ribbon after heat-treatment . The magnetoimpedance change (Z(H=65 Oe )−Z(0))/Z(0) for the longitudinal case can reach the value of −41.78%.

Magnetostriction influence on the giant magnetoimpedance effect: a key parameter

Journal of Magnetism and Magnetic Materials, 2004
No actual explanation for the relatively low limit of the giant magnetoimpedance effect (GMI), in magnetostrictive materials, is now available. Neither the damping of the domain walls nor the dynamics of the magnetization rotation lead to values in agreement with the experience. In this paper we study the magnetoelastic influence on GMI.

Giant Magnetoimpedance Effect: Concept and Prediction in Amorphous Materials

Journal of Superconductivity and Novel Magnetism, 2012
Giant magneto impedance (GMI) effect was experimentally measured on as-cast, post-production and coated with chemical technique amorphous wire and ribbon materials consisted of varied chemical composition over a frequency range from 0.1 to 8 MHz under a static magnetic field between −8 and +8 kA/m.

Magnetic Properties and Giant Magnetoimpedance Effect in Nanocrystalline Microwires

2014
We studied GMI effect and magnetic properties of Finemet-type FeCuNbSiB microwires. We observed that GMI magnetic field and frequency dependences and magnetic softness of composite microwires produced by the Taylor-Ulitovski technique can be tailored either controlling magnetoelastic anisotropy of as-prepared FeCuNbSiB microwires or controlling their ...

Asymmetric giant magnetoimpedance effect created by micro magnets

Journal of Magnetism and Magnetic Materials, 2018
Abstract Asymmetric giant magnetoimpedance (AGMI) effect has been investigated in as-prepared and current annealed amorphous (Co0.9Fe0.05Ni0.05)75Si15B10 ribbons. Asymmetry was created by micro magnets. Different numbers of magnets were used and it was found that increasing number of magnet, the shift in AGMI curves increases.

Giant transversal magnetoimpedance and Hall-effect measurements in Co70.4Fe4.6Si15B10

Journal of Applied Physics, 1996
We report room-temperature transversal magnetoimpedance (TMI) and Hall-effect measurements performed in ribbons of the zero-magnetostriction soft-ferromagnet Co70.4Fe4.6Si15B10 alloy annealed at 587 K for 15 min at a dc magnetic field of 2 kOe. The annealing showed little effect on the magnetostriction of the samples.

Domain wall permeability limit for the giant magnetoimpedance effect

Journal of Applied Physics, 2002
The magnetoimpedance (MI) effect is based on the change of inductance and resistance under the effect of an external magnetic field. In bulk homogeneous wires or ribbons these two components of the impedance are related to the penetration depth of the electromagnetic field in the material.

Giant magnetoimpedance effect in Fe75.5Cu1Nb3Si13.5B7 ribbon/FeGa film composite

Journal of Magnetism and Magnetic Materials, 2016
Abstract Optimized giant magnetoimpedance effect of Fe 75.5 Cu 1 Nb 3 Si 13.5 B 7 amorphous ribbon/Fe 80 Ga 20 film composites has been investigated. FeCuNbSiB amorphous ribbons as the substrates are commercially available, magnetostrictive FeGa films are deposited on one or both sides of the ribbons by ion-beam sputtering.
