SIMULACIONES DE COMPORTAMIENTOS HISTERÉTICOS BLANDOS EN PELÍCULAS MAGNÉTICAS.

This paper deals with calculations of hysteresis loops in soft magnetic materials. We obtain the hysteresis loops by means of the Jiles-Atherton model. The influence of domain walls pinning on the form of the loops and coercivity has been discussed. The theoretical hysteresis loops are compared with experimental hysteresis loops for NiZn ferrites thin films. The loops have been calculated by the expression: Mi = M[Mi-1(Hi-1),Hi] + C.
