Magnetic domain structure in amorphous glass-covered wires with positive magnetostriction

Abstract

Experimental investigation of the domain structure in Fe/sub 77.5/Si/sub 7.5/B/sub 15/ amorphous glass-covered wires by Kerr microscopy is reported for the first time. A single domain configuration with axial easy axis was observed in glass-covered samples. After glass removal, a maze domain configuration appears at the wire surface, while the axially magnetized domain still exists within the wire's inner region.
