Modeling of the magnetocrystalline cubic anisotropy in Fe-Si electrical steels

Abstract

In this paper the modeling of the cubic anisotropy due to the crystal grain structure in Fe-Si steels has been developed by means of an analytical approach derived from the classical Stoner and Wohlfarth model. The magnetic behaviour of a circular Fe-Si particle that is assumed to be single crystal, is computed by both a micromagnetic simulator and the analytical model implemented.
