Fig. 5: Energy dependence of the pump effect on reflectivity and x-ray magnetic circular dichroism in reflectivity (XMCDR).

Reflectivity and XMCDR spectra at ((a) Delay=100 ps; (b) Delay=1400 ps). Normalized XMCDR and reflectivity spectra at different delay time ((c) XMCDR, 100 ps; (d) XMCDR, 1400 ps; (e) Reflectivity, 100 ps; (f) Reflectivity, 1400 ps). Curves in (c–f) are normalized to the corresponding unpumped values.
