Anomalous magnetic behavior in half-metallic Heusler Co2FeSi alloy glass-coated microwires with high Curie temperature
(Elsevier, 2022-11)
In the current study, we have succeeded to fabricate Co2FeSi Heusler alloy glass-covered microwires with magnetic core nucleus diameter d = 4.36 mu m and total diameter D = 17.55 mu m, with high Curie temperature (T-e > ...
Effect of applied stresses on magnetic properties of Co and Fe-rich glass-coated microwires
(AIP, 2023-03)
In this article we evaluate the possibility of using glass coated magnetic microwires as an alternative to optical fiber devices in structural health monitoring in the railway industry. The effect of applied stress on ...
Determination of Magnetic Structures in Magnetic Microwires with Longitudinally Distributed Magnetic Anisotropy
(MDPI, 2023-03-13)
We studied the magnetic properties of a glass-covered amorphous microwire that was stress-annealed at temperatures distributed along the microwire length. The Sixtus-Tonks, Kerr effect microscopy and magnetic impedance ...

Giant magnetoimpedance, GMI, effect and magnetic properties upon temperature influence of as-prepared and stress-annealed amorphous
Fe75B9Si12C4 glass-coated microwires produced by the Taylor-Ulitovsky technique are ...
Optimization of Magnetoimpedance Effect and Magnetic Properties of Fe-Rich Glass-Coated Microwires by Annealing
(MDPI, 2023-08-28)
As-prepared Fe-rich microwires with perfectly rectangular hysteresis loops present magnetization reversal through fast domain wall propagation, while the giant magnetoimpedance (GMI) effect in Fe-rich microwires is rather ...
Electronic Surveillance and Security Applications of Magnetic Microwires
(MDPI, 2021-04-30)
Applications in security and electronic surveillance require a combination of excellent magnetic softness with good mechanical and anticorrosive properties and low dimensionality. We overviewed the feasibility of using ...
Engineering of domain wall propagation in magnetic microwires with graded magnetic anisotropy
(Elsevier, 2022-03)
[EN] We report on the influence of graded magnetic anisotropy designed by stress-annealing of magnetic microwire at variable annealing temperature on domain wall propagation. We found that the domain wall propagation in a ...
Development of Magnetic Microwires for Magnetic Sensor Applications
(MDPI, 2019-11-02)
Thin magnetic wires can present excellent soft magnetic properties (with coercivities up to 4 A/m), Giant Magneto-impedance effect, GMI, or rectangular hysteresis loops combined with quite fast domain wall, DW, propagation. ...
Optimization of magnetic properties and GMI effect of Thin Co-rich Microwires for GMI Microsensors

Magnetic microwires can present excellent soft magnetic properties and a giant magnetoimpedance effect. In this paper, we present our last results on the effect of postprocessing allowing optimization of the magnetoimpedance ...
Engineering of Magnetic Softness and Domain Wall Dynamics of Fe-rich Amorphous Microwires by Stress- induced Magnetic Anisotropy
(Nature Publishing, 2019-08-27)
We observed a remarkable improvement of domain wall (DW) mobility, DW velocity, giant magnetoimpedance (GMI) effect and magnetic softening at appropriate stress-annealing conditions. Beneficial effect of stress-annealing ...
