A magnetic field sensor was developed using the asymmetric giant magnetoimpedance (AGMI) effect. Amorphous ferromagnetic (Fe0.06Co0.94)72.5Si12.5B15 wires were used in this study. The 2-cm-long wire showed an approximately 88% effect, and 7-cm-long 197% When two micromagnets placed 1 cm from ends of wire, a distortion peak shapes GMI curve observed, asymmetry created by micromagnets. 148% AGMI ...

Amorphous magnetic microwires can be suitable for a variety of technological applications due to their excellent softness and giant magnetoimpedance (GMI) effect. Several approaches optimization soft properties GMI effect covered with an insulating, flexible, biocompatible glass coating tunable are overviewed. The high properties, achieved even in as-prepared Co-rich vanishing magnetostriction ...
