Abstract

The Alessandro, Beatrice, Bertotti, and Montorsi (ABBM) model can describe the dynamics of domain wall motion in a ferromagnetic material which is subjected to a smoothly varying external magnetic field. The assumptions of this model limit its use to experiments where the differential permeability and time derivative of applied field are constant. In this paper, the non-linear permeability of the sample is incorporated into the ABBM model by extracting the differential permeability at different points on the B,H plane from the Jiles-Atherton (J-A) hysteresis model.
