Figure 10
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[link]) 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.
