Abstract

Numerically efficient Preisach-based vector hysteresis models for ellipsoidally magnetizable media are presented. Both models are based on orthogonal coupled scalar models and take into consideration the variation in particle switching fields and interaction; however, the coupling mechanism is different in the two models. The rules determining the magnetization state corresponding to the vector applied field are discussed. The basic rotational remanence properties of the models are compatible with observed vector phenomena
