A contribution to 2D vector Preisach modelling

A vector hysteresis model, combining the classical Preisach and Stoner-Wohlfarth models, has been developed. It is derived by superposition of Preisach models with axes dispersed in a plane. The Preisach planes are modified, defined by the actual particles' switching fields. They are calculated by the SW astroid, shifted along the easy axis to account for interactions. Both reversible and irreversible changes are considered. The model performs well in simulating experimental data.
