摘要 飞秒激光抽运探测在超快磁动力学的研究中有十分广泛的应用。当前在超快磁动力学的研究中,根据抽运光对样品激发方式的不同,主要分为两类:(1)光激发下的磁动力学;(2)磁场激发下的磁动力学。介绍了这两种激发模式下的磁动力学的最新研究进展,并对未来的研究方向进行了展望。 Femtosecond lasers have been widely employed to investigate the ultrafast magnetic dynamics. The femtosecond laser pulse as the pump source has two different ways to stimulate samples: (Ⅰ) optical pump; (Ⅱ)magnetic field pump .The development of ultrafast magnetic dynamics in the two different stimulation ways are introduced, and the research trend is predicted.
