Spectra were normalized to the integrated fluorescence intensity from energy loss 4 to 12 eV. a, c Energy vs temperature RIXS maps measured on SC28K and SC42K, respectively. The elastic peak was subtracted to manifest the low-energy excitations. b, d The waterfall plots correspond to (a) and (c), respectively. Examples of the fitting components are shown in the bottom spectra. e–h Temperature dependence of the fitted integrated intensity of these four Raman features, respectively. The integrated intensity was normalized to that of 25 K for comparison. Temperature evolution of the spectral weight of dxy orbital measured by ARPES in monolayer FeSe/STO (green markers) is shown in (g) for comparison12.
