Effect of Joule heating on GMI and magnetic properties of Fe-rich glass-coated microwires

AIP Advances, 2022
Influence of Joule heating on magnetic properties and GMI effect of Fe75B9Si12C4 glass-coated microwires was studied. A decrease in coercivity after Joule heating is observed, while hysteresis loops of Joule heated samples maintain a rectangular shape ...

Off-Diagonal Magnetoimpedance in Annealed Amorphous Microwires with Positive Magnetostriction: Effect of External Stresses

Magnetism, 2023
It was observed recently that the giant magnetoimpedance (GMI) effect in Fe-rich glass-coated amorphous microwires with positive magnetostriction can be improved significantly by means of post-annealing.

High frequency properties of glass-coated microwire

Journal of Applied Physics, 1998
Static and high-frequency 1–30 MHz properties of the (Co100−xMnx)75B15Si10 microwires cast using the modified Taylor’s technique are reported. The hysteresis loop and the frequency dependence of permeability indicate that the longitudinal magnetization process occurs by coherent rotation of the moments.

Magnetic Microwires With Field-Induced Helical Anisotropy for Coil-Less Fluxgate [PDF]

, 2010
We present a new method for production of magnetic microwire with helical anisotropy. Coil-less fluxgate sensors are generally composed of a bimetallic wire excited by an alternating current; in order for the wire to work in coil-less fluxgate mode, the ...

Preparation and properties of glass-coated microwires

Journal of Magnetism and Magnetic Materials, 2002
Abstract Technological aspects of the Taylor–Ulitovsky method for fabricating glass-coated microwires with different structures of metallic nucleus are discussed. The main parameters of the process can be distinguished as follows: a casting rate of microwire and its limits, cooling rate of the metal core, geometrical characteristics and alloy ...

Domain wall mobility engineering by a perpendicular magnetic field in microwires with a gradient of perpendicular anisotropy

AIP Advances, 2021
Fast domain wall propagation is a typical feature of amorphous glass-coated microwires with positive magnetostriction. The high domain wall velocity can be effectively tailored either by sample postprocessing or temperature.

Magnetic Properties of Glass-Coated FeWB Microwires

Acta Physica Polonica A, 2014
We have studied magnetization process in amorphous bistable Fe80W3B17 microwires with reduced Curie temperature. High mechanical stresses from glass-coating, induced during production process, result in high switching eld. Reducing the length of microwire, the switching eld decreases as a result of reduction of magnetoelastic anisotropy.
