Giant magnetoimpedance effect in melt-spun Co-based amorphous ribbons and wires with induced magnetic anisotropy

GMI in Co 68.25Fe 4.5Si 12.25B 15 melt-spun amorphous wires and ribbons has been studied. Selected samples have been submitted to DC Joule-heating to induce circular and transverse magnetic anisotropy. Hysteresis loops have been measured using a fluxmetric technique.

Zusammenfassung:GMI in Co 68.25Fe 4.5Si 12.25B 15 melt-spun amorphous wires and ribbons has been studied. Selected samples have been submitted to DC Joule-heating to induce circular and transverse magnetic anisotropy. Hysteresis loops have been measured using a fluxmetric technique. The results were interpreted in terms of circumferential and transverse permeability correlated with the magnetic domain structure.
