摘要：

Ultrafast control of thin film nanomagnets using femtosecond laser pulses has attracted considerable attention for future ultrafast and energy-efficient photo-spintronics storage=memory devices. Single femtosecond laser pulse magnetization switching without an applied external magnetic field has been recently observed on various metallic thin films. Herein, a recent understanding of the physical mechanism behind single-shot all-optical magnetization switching and perspectives are described.
