Generalized Preisach model of hysteresis

Abstract

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.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
