Abstract :
In the framework of rate-independent magnetization, this paper deals with an alternative approach to the bi-dimensional m-model, which uses analytical Preisach function instead of numerical characterization. Starting from the knowledge of experimental major loop for easy and hard axes we are able to characterize the parameters of the Lorentzian function.
