Computer-aided simulation of Stoner–Wohlfarth model

Abstract The simulation of magnetic phenomena in anisotropic materials has several difficulties. The Stoner–Wohlfarth model can describe the magnetisation process in anisotropic materials. In this paper the magnetisation behaviour of the Stoner–Wohlfarth particle will be studied in linear excitation and in rotational magnetic field. The variation of the magnetisation vector can have jumps, these jumps correspond to the Barkhausen effect. The vector hysteresis model will be developed.
