Generalized Preisach model of hysteresis

The model has the following advantages over the classical Preisach (1935) model. First, it relaxes the congruency property of the classical model, which results in a broader area of applicability. For example, the hysteresis loops exhibited by the Stoner-Wohlfarth (1948) magnetic particles can be described by the nonlinear model, while they are not covered by the classical model. Second, the nonlinear model allows one to fit first- and second-order transition curves, while the classical model allows only for fitting of first-order transition curves. As a consequence, the nonlinear model is more accurate. >
