TR-XRD of the (–101) FeRh Peak—(a) Peak intensity and 2θ shift as a function of probe delay for the FeRh (–101) XRD peak. The extracted quantities show similar dynamics, initially decaying within 10–30 ps and recovering over 100’s of ps. (b) The same quantities focusing on the initial excitation up to 15 ps. For fluences 5.5 mJ cm-2 and above, the peak shift shows different dynamics to that of the intensity, with increasing divergence for increasing fluence.
