Abstract
Laborious surface polishing has been inevitably necessary for domain observations of bulk magnetic materials by Kerr effect. We have made it possible to observe the magnetic domain without any surface polishing for bulk magnetic materials. A CCD (charge coupled device) image sensor and a microcomputer did the contrast enhancement and noise reduction. Domains in rapidly quenched amorphous magnetic materials have been observed clearly without any surface polishing.This publication has 3 references indexed in Scilit:
