Abstract :
In this paper, we present a new Preisach-type model that can be successfully applied to simulate complex magnetization processes for strongly correlated particulate systems. As suggested by micromagnetic simulations, the Preisach distribution of interaction fields has a two peak shape and the amplitude of the peaks is dependent of the magnetic state of the sample. The model is compared with the simulations made with a variable variance Preisach model, and the results are discussed.
