Abstract
We present an inclusive macroscopic model of ferromagnetic hysteresis. We developed the model from a Stoner-Wohlfarth approach by adding the mean-field or nearest-neighbor interactions and the effect of pinning. The model includes features of the Jiles-Atherton model in the previous Atherton-Beattie extension of the Stoner-Wohlfarth model, but still omits the domain wall energy effects included in the Globus model. The model describes both reversible and irreversible processes and hysteresis caused by combinations of interaction, anisotropy, and pinning. We outline computational approaches and give examples.
