Magnetic properties of Fe-based amorphous magnetic microwires

The magnetic characteristics of Fe-based cast amorphous glass-coated microwires (with a positive magnetostriction constant) have been studied. The residual stress distributions in this type of microwires determine the domain structures and the switching field behavior. These wires are characterized...
