概要
- 論文の詳細を見る
It has been demonstrated recently that the magnetization of a nano magnet can be switched by spin-transfer effect within 200 ps. This result is promising for the application of spin-transfer effect to magnetic random access memory. Contrary to thermally-assisted reversal, the switching process slows down with increasing temperature. We analyze these results in terms of a phenomenological model which takes into account the incoherent precession of the magnetization. The results suggest that coherent precession is a key to realize ultra fast switching.
