| 英文摘要 | The ultrafast dynamics of in-plane four-state magnetization reversal from compressively strained (ga,mn)as film was investigated by magneto-optical kerr rotation measurement. the magnetization reversal signal was dramatically suppressed upon pumping, and recovered slowly with time evolution. the low switching field h-c1 increased abruptly from 30 to 108 g on the first several picoseconds and recovered back to the value before optical pumping within about 500 ps, whereas the high switching field h-c2 did not change obviously upon pumping, implying a domain-wall nucleation/propagation at low fields and coherent magnetization rotation at high fields in the magnetization reversal process. |
