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 …
