Hysteresis modeling: II. Accommodation

Preisach modeling, which has been used to describe hysteresis in magnetic devices, especially those used in magnetic recording, is unable to describe certain phenomena. This paper deals with one of these phenomena, accommodation, in which it takes many cycles for a minor hysteresis loop to stabilize. It is shown how both the "moving" model and the "product" model can be modified, in order to demonstrate this property.
