Inset: intensity of the magnetic scattering pattern collected by the 2D+t detector showing the ring-shaped resonant magnetic scattering contribution from the worm-like domains in the CoPd multilayer. Note that this pattern has been accumulated by selecting uniquely the photons emitted by the electron bunch following the laser excitation (see Fig. 1) and normalized to the intensity recorded for revolutions preceding the laser excitation. The intensity integrated over the ring is plotted as a function of the IR pump/X-ray probe delay, thus characterizing the magnetization dynamics at the Co L3-edge (778 eV) following the laser excitation. |
