Effect of nanocrystallization on Giant magnetoimpedance effect of microwires
2013 Seventh International Conference on Sensing Technology (ICST), 2013We 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 ...

Giant magnetoimpedance effects in the amorphous ribbon Fe8.0Co62.4Mn0.5Mo0.6Ni0.5Si14.7B13.3
Materials Science and Engineering: B, 1999Abstract In the present work, the experimental results indicate that both resistive and inductive components of the impedance for the ribbon Fe8.0Co62.4Mn0.5Mo0.6Ni0.5Si14.7B13.3 are influenced strongly by the frequency of the ac drive current and dc magnetic fields in the longitudinal and transversal direction, respectively.

Giant magnetoimpedance effect in Ag/NiFe plated wire
Materials Science and Engineering: B, 2004Abstract In the present work, the giant magnetoimpedance (GMI) effect of Ag/NiFe plated wire was investigated at room temperature. The value of the magnetoimpedance (Z(H)−Z(0))/Z(0) under H=90 Oe can reach about 40% at 50 kHz. With the increase of the field the magnetoimpedance (Z(H)−Z(0))/Z(0) reaches a peak. The peak-field HP increases firstly with

Giant magnetoimpedance effect in nanocrystalline Fe74SixB22−xCu1Nb3 ribbons
Journal of Applied Physics, 1997We investigated the magnetoimpedance (MI) effect for the soft magnetic nanocrystalline Fe74SixB22−xCu1Nb3 (x=4–18) alloys, and also the relationship between the magnetic properties and the MI effect. The annealing temperature dependence of the MI ratio corresponds to that of the permeability of longitudinal direction of the samples.

Giant magnetoimpedance effect in soft magnetic wire families
IEEE Transactions on Magnetics, 2002Summary form only given. The giant magneto-impedance (GMI) effect-an abrupt change in the high frequency impedance of a magnetic conductor subjected to a relatively small dc magnetic field-has been widely studied in the last several years. GMI effect investigations performed on various soft magnetic wire families have demonstrated that such materials ...

Magnetic field meter based on giant magnetoimpedance effect
Sensors and Actuators A: Physical, 2008The giant magnetoimpedance (GMI) effect in Co-based amorphous ribbon was investigated. In order to improve the properties of its magnetoimpedance characteristics, with respect to their application as a sensing element, the ribbon samples were subjected to various thermal and mechanical treatments.

Giant magnetoimpedance effect in Fe–Nb–B ribbon
Solid State Communications, 1999Abstract 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%.

Asymmetric giant magnetoimpedance effect created by micro magnets
Journal of Magnetism and Magnetic Materials, 2018Abstract 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.

Anisotropic magnetoresistance and giant magnetoimpedance effects in soft magnetic fibers
Journal of Magnetism and Magnetic Materials, 1996Abstract Soft magnetic fibers with different compositions have been cast by melt extraction. An anisotropic magnetoresistance effect (AMR) of about 3% was measured in NiFe fibers and employed to propose a model for their anisotropy and magnetization process.

Giant magnetoimpedance effect in Fe75.5Cu1Nb3Si13.5B7 ribbon/FeGa film composite
Journal of Magnetism and Magnetic Materials, 2016Abstract 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.
