Enhanced high-frequency magneto-impedance response of melt-extracted Co69.25Fe4.25Si13B13.5 microwires subject to Joule annealing

Journal of Science: Advanced Materials and Devices, 2016
We report an enhancement of low-field, high-frequency magneto-impedance (MI) response and circumferential domain structures of melt-extracted amorphous Co69.25Fe4.25Si13B13.5 microwires by dc Joule annealing. The current amplitudes of 5 mA, 10 mA, and 20

An Indirect Method of Micromagnetic Structure Estimation in Microwires

Nanomaterials, 2021
The tunable magnetic properties of amorphous ferromagnetic glass-coated microwires make them suitable for a wide range of applications. Accurate knowledge of the micromagnetic structure is highly desirable since it affects almost all magnetic properties.

Domain Wall Dynamics in Amorphous Microwires

Acta Physica Polonica A, 2008
Here we present the domain wall dynamics in FeNi-based microwires with positive magnetostriction. Two different ranges were found which differs by the measured domain wall mobility. At low fields, the domain wall dynamics exhibit small mobility, whereas at higher field the domain wall mobility increases.
