Structural and magnetic anisotropy of directionally-crystallized ferromagnetic microwires

EPJ Web of Conferences, 2018
Amorphous ferromagnetic microwires have drawn attention primarily due to their excellent soft magnetic properties as the elements of sensors. In this work, semi-hard magnetic microwires of composition Fe4.3Co67.7Si11B14Cr3 were obtained after a process ...

Optimization of the high-frequency magnetoimpedance response in melt-extracted Co-rich microwires through novel multiple-step Joule heating

Journal of Science: Advanced Materials and Devices, 2021
The optimization of the high frequency giant magnetoimpedance (GMI) effect and its magnetic field sensitivity in melt-extracted Co69.25Fe4.25Si13B12.5Nb1 amorphous microwires was systematically studied through a multi-step Joule annealing (MSA) technique.
