Method of analysis of the reversal magnetization processes using magnetic domain structure images

Abstract

A unique software and hardware system for obtaining and automatic analysis of the magnetic domain structure images in an external magnetic field for further study of the magnetization reversal process was developed. The method efficiency and possibility of its use for studying the magnetization reversal of local surface regions of magnetic materials are shown, using the experimental magnetization curves of an yttrium-iron garnet film.
