MIXED-TYPE MODELS OF HYSTERESIS

The hysteresis models are currently classified in two categories: physical and phenomenological models, A new model-type, referred to as mixed-type model, is introduced. In mixed-type models starting from the hysteresis loop model for the ferromagnetic particles as well as from their distributions as a function of orientation, anisotropy and interaction field, an equivalent distribution of pseudo-particles is computed. Each pseudo-particle is associated to a certain small zone of the Preisach plane. Since in the first stage the model is a physical-type model and in the second it becomes similar to a phenomenological Preisach-type model, it was named mixed-type model. An efficient numerical implementation of the static generalized interacting particle system (IFS) model is presented. A comparison of experimental and simulated data is provided.
