Abstract
We have used timeresolved xray magnetic circular dichroism combined with photoemission electron microscopy XMCDPEEM to investigate the layerresolved microscopic magnetization reversal in FeNi/X/Co with X=Cu Al2O3 trilayer systems These measurements were performed in pumpprobe mode synchronizing magnetic pulses with synchrotron xray pulses The good magnetic contrast observed for most samples reveals that in many cases the magnetization reversal is reproducible We have used the measurements to obtain domain wall propagation speeds as a function of applied magnetic field and to investigate the influence of domain wall interactions on the magnetic switching
