报告摘要：
Deterministic magnetization switching induced by a single femtosecond or picosecond laser pulse, resulting from the direct interaction between the ultra-short laser pulse and the magnetization has been reviewed recently in [1]. They have demonstrated that light can generate spin-polarized femtosecond current pulses to reverse the magnetization of thin ferromagnetic films in magnetic heterostructure [2-7]. They have shown ultra-fast magnetization reversal (in less than one pico-second) [3] in various perpendicularly magnetized ferrimagnetic and ferromagnetic spin-valve structure [4-7]. Those results open the field of ultra-fast spintronics.
