Abstract: Ultrashort, coherent x-ray pulses of a free-electron laser are used to holographically image themagnetization dynamics within a magnetic domain pattern after creation of a localized excitation via anoptical standing wave. We observe a spatially confined reduction of the magnetization within a couple ofhundred femtoseconds followed by its slower recovery. Additionally, the experimental results showevidence of a spatial evolution of magnetization, which we attribute to ultrafast transport of nonequilibrium spin-polarized electrons for early times and to a fluence-dependent remagnetization rate for later times.
