Development of Magnetically Soft Amorphous Microwires for Technological Applications

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 coefficient, further improved by appropriate heat treatment (including stress-annealing Joule heating). Although Fe-rich amorphous exhibit low ratio rectangular hysteresis loops, stress-annealing, heating, combined stress-annealed followed conventional furnace annealing substantially improve the (by more than order magnitude).
