摘要：

Nonvolatile high-speed optical memory is proposed, which utilizes the magnetization reversal of nanomagnet by spin-polarized photoexcited electrons. It was demonstrated experimentally that one selected pulse from the train of two optical data pulses with interval of 450 fs can solely excite the spin-polarized electrons without a disturbance from the unselected optical data pulse. That proves feasibility for operation of the memory with speed of 2.2 Tbits/s.
