a Sketch of the laser-driven plasma source and the scattering setup. The SAXS pattern detected by a fast-readout area detector together with the direct beam is shown in panel (d). b Magnetic force microscopy image of the magnetic domain pattern in the FeGd multilayer. c, d The time-resolved SAXS signal detected at the Gd M5 absorption edge (1189 eV photon energy). The composite image in (d) shows the sum of detector frames taken before laser excitation (t < 0 ps, left) and frames taken after laser excitation (35 ps < t < 685 ps, right). For data analysis, the 2D detector frames are azimuthally integrated as shown in (c). The 1st and 3rd order maxima of the scattering intensity are indicated in both panels
