The Influences of Size and Anisotropy Strength on Hysteresis Scaling for Anisotropy Heisenberg Multilayer Films

Abstract:

In this paper, we simulate the magnetization dynamic processes of the multilayer films, and calculate their hysteresis loop areas using Monte Carlo method. The simulated results indicate that, the size and anisotropy strength of the anisotropy multilayer films influence evidently the dynamic phase transition, and the phase transition temperature increases with enhancing values of the anisotropy constant and layer thickness. It is also found that, with increasing number of layers of films, the value of α decreases, while the magnitudes of β and γ increase. On the contrary, with increasing anisotropy strength, the value of α increases, while the magnitudes of β and γ reduce.
