Evaluation of magnetostrictive effects in soft magnetic materials using the Preisach theory

Abstract The shape of the Preisach function P ( α , β ) is discussed for the study of magnetostrictive hysteresis for grain oriented SiFe-alloys. To this end, the distribution function is identified in such a way that P ( α , β )=− P (− β ,− α ). The model is validated by comparison of numerical experiments and measurements obtained for a single sheet set-up using optical methods.
