We present a compact sample holder equipped with electromagnets and high frequency transmission lines; the sample holder is intended for combined x-ray magnetic circular dichroism (XMCD) and ferromagnetic resonance measurements (FMR). Time-resolved measurements of resonant x-ray detected FMR during forced precession are enabled by use of a rf excitation that is phase-locked to the storage ring bunch clock. Several applications of the combined XMCD+FMR technique are presented, demonstrating the flexibility of the experimental design.
我们展示了一种配备电磁铁和高频传输线的紧凑型样品架；该样品架旨在用于结合X射线磁性圆二色性（XMCD）和铁磁共振测量（FMR）。通过使用与存储环束团时钟锁相的射频激励，能够在强制进动期间对共振X射线检测到的FMR进行时间分辨测量。展示了结合XMCD+FMR技术的几种应用，证明了实验设计的灵活性。
