Abstract: Aiming at nondestructive evaluation of magnetic materials, Monte Carlo simulations of the dynamic magnetic processes were investigated on the temporal and the temperature dependences for spin systems with various lattice imperfections as so called Barkhausen noises. From a physical point of view, the presented method might be the more useful tool for the analyses of the dynamic magnetic processes rather than those by Preisach model.
