Surface magnetization reversal and magnetic domain structure in amorphous microwires

摘要

This paper presents a review on magneto-optical investigations of the glass-coated amorphous microwires including magneto-optical magnetometry and microscopy. We also discuss a Kerr-effect method of domain-wall-motion detection in glass-coated wires within a classical Sixtus-Tonks experimental scheme. The developed techniques make it possible to observe the surface magnetization reversal and to establish the main mechanisms of domain-structure formation and transformation.
