摘要

利用双高速摄影技术表明，外部磁场触发GdFeCo畴壁的运动速度可达1.2 km/s。畴壁速度随驱动磁场脉冲幅值的增大而增大并趋于平稳。与先前的铁铁氧体实验相反，即使泵浦脉冲能量足以磁化反转，飞秒激光脉冲对畴壁动力学的影响也没有被观察到。

Study of Domain Wall Dynamics in GdFeCo Using Double High-Speed Photography

It is shown using the technique of double high-speed photography that an external magnetic field triggers the motion of a GdFeCo domain wall with a velocity up to 1.2 km/s. The domain wall velocity increases and levels off with an increase in the amplitude of the driving magnetic-field pulse. In contrast to the earlier experiments on iron ferrites, no influence of femtosecond laser pulses on the domain wall dynamics has been observed, even when the pump pulse energy is sufficient for magnetization reversal.
