Extreme ultraviolet light sources based on high-order harmonic generation (HHG) have recently been used to investigate magnetization dynamics on the femtosecond timescale with element selectivity. In these studies the photon energy has been tuned to the M-absorption edges of Fe, Co and Ni located at 52 eV, 61 eV and 67 eV. In addition, HHG sources are well suited for resonant magnetic scattering (RMS) experiments, where magnetic domains can be resolved with nanometer precision. We present RMS investigations of Co/Pt multilayer films before and after an intense laser illumination and discuss the influence of laser-induced modifications on the scattering image.
