Hysteresis models for the description of domain wall motion

A physically based hysteresis model for materials where magnetic domain wall motion is the main magnetization mechanism is presented. The behavior of a single domain wall (DW) is described by a restriction of the Preisach model and the superposition of many DW contributions is then treated by introducing a multiplicative factor describing the dependence of the DW surface on magnetization. This model exhibits wiping-out property and a new kind of minor loop congruency
