Giant magnetoimpedance in the ferromagnetic amorphous alloys

AIP Conference Proceedings, 2020
In this work, rapidly quenched amorphous cobalt-based ribbons with a metalloid content of 20% and the finemet type ribbons were investigated in as-quenched state. Their structure, magnetic properties magnetoimpedance (MI) behaviour were discussed in the context of the effective magnetic anisotropy peculiarities depending on the length of the ribbons ...

Giant magnetoimpedance effect in sandwiched films

Journal of Applied Physics, 1999
The giant magnetoimpedance (GMI) effect in films with a sandwiched structure has been studied. FeNiCrSiB/Cu/FeNiCrSiB sandwiched films with a magnetic closed-loop structure were deposited onto a glass substrate by rf sputtering and then annealed at an optimum temperature.

Giant magnetoimpedance in FeAg granular alloys

Applied Physics Letters, 2002
We have observed giant magnetoimpedance (GMI) in an FeAg granular alloy. Impedance and transverse susceptibility (TS) measurements as a function of the external dc magnetic field were made at room temperature. The variation of the magnetoimpedance ratio with magnetic field has been related to a corresponding TS ratio change as a function of the ...

Giant Magnetoimpedance Sensors and Their Applications

2016
Since GMI changes as a function of external dc magnetic field or applied dc/ac current, it is possible to design and produce GMI-based sensors that can measure either magnetic fields or dc/ac currents. GMI also changes sensitively with applied stress, and this provides a new opportunity to develop stress sensors.

Recent experiments and models on giant magnetoimpedance

Physica B: Condensed Matter, 2002
An overview of the giant magnetoimpedance phenomenon is given in this work. The effect, that consists of drastic changes of the complex impedance of soft magnetic materials upon the application of an external magnetic field, has attracted attention owing to the increasing perspectives of applications on magnetic and stress sensor technology.
