Vector Hysteresis Model at Micromagnetic Scale

In this paper we discuss about the possibility to reproduce the behavior of a magnetic material at micromagnetic scale with a phenomenological vector model of hysteresis based on the definition of a vector hysteron. We compare data computed by means of two different static magnetic models. The former is based on the solution of Brown´s equation (micromagnetic scale). The latter is a vector generalization of the Classical Scalar Preisach Model (macromagnetic scale). We show that the magnetization versus applied field curves computed by both models are in good agreement, and that the macromagnetic-scale model is able to reproduce the physical behavior of the magnetic materials at micromagnetic scale
