Some remarks about the magnetization processes in electrical steels via a micromagnetic approach

Abstract

In this work the magnetic behaviour of Fe-Si alloys is investigated at microscopic scale in order to better understand the physical mechanisms which govern the magnetization phenomena in such materials. The analysis is carried out on thin Fe-Si films with uniaxial anisotropy by means of both a micromagnetic simulator and the Stoner-Wohlfarth model. The conditions under which the Stoner-Wohlfarth approximation can be operated in reproducing the magnetization processes of anisotropic steel films are discussed.
