Abstract :
Experimental investigation of the domain structure in Fe77.5 Si7.5B15 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
