Using a fast silicon strip detector, a multi-frame acquisition scheme was implemented to perform energy-dispersive X-ray magnetic circular dichroism at the iron K-edge in pulsed high magnetic fields. The acquisition scheme makes use of the entire field pulse. The quality of the signal obtained from samples of ferrimagnetic erbium iron garnet allows for quantitative evaluation of the signal amplitude. Below the compensation point, two successive field-induced phase transitions and the reversal of the net magnetization of the iron sublattices in the intermediate phase were observed.
使用快速硅条探测器，实现了一种多帧采集方案，以便在脉冲强磁场中进行铁 K 边缘的能量色散 X 射线磁圆二色性测量。采集方案利用了整个磁场脉冲。从亚铁磁铒铁石榴石样品中获得的信号质量允许对信号幅度进行定量评估。在补偿点以下，观察到两个连续的场诱导相变和中间相中铁亚晶格净磁化强度的反转。
