摘要：

The dynamic response of magnetization under a rapidly varying applied field was analyzed using the Landau-Lifshitz equation. The computed angular dependence of the lower bound of the dynamic switching field is found to be less than the static limit and, moreover, it is asymmetric with respect to 45 degrees deflection of the applied field. Oscillatory switching occurs between the dynamic and static thresholds. The width of the reversal bands depends on the damping rate and rise time of the field.
