| Abstract(in English) | In this paper, the effect of mesh size on the equilibrium magnetization configurations and the switching behavior are calculated by employing cubic particles with numerical micro-magnetics. The sizes of the cubic particles D are varied from 200A to 600A. Each particle is divided into 3×3×3, 5×5×5,7×7×7 and 9×9×9 cubic elements. respectively. The remanent state may change from flower state to vortex state at about 500 A (3×3×3 case), 520 A (5×5×5 case), 530 A (7×7×7 and 9×9×9 cases). For D < 500A, switching occurs by uniform rotation with different meshes. For 500A < D < 530A, a finer mesh generates uniform rotation while a crude generates nonuniform rotation. The angular dependence of the coercivity field and switching field with different meshes are also given. |
