Abstract

Monte Carlo method has been applied to simulate the hysteresis loops from VSM and MOKE measurement for Ni_xSiO_2(1-x)granular films. The simulated results reveal that: (1) The calculated Kerr loops are in good agreement with the experimental data. (2) The anisotropy constant decreases with the increasing packing fraction of Ni clusters; (3) Generally, the difference between the hysteresis loops obtained from VSM and Kerr effect respectively always exists for the finite incident angle. It increases with increasing incident angle. It for strong ferromagnetic films is smaller than those for weak or mixed magnetic films.
