摘要：

We present a computational study of magnetization reversal in narrow rings when a field pulse is applied perpendicular to the magnetization. Reversal proceeds by domain wall motion and is completed in 500 ps approximately. The reversal mechanism is found to be stable for a wide range of applied fields and pulse widths.
