(a) The Co L3-edge XAS spectrum collected using fluorescence yield. Red and the blue bars mark the energy windows where the RIXS spectra were acquired. (b, c) Low-energy excitations in CoO as a function of the hvin-integration window for the region marked in red (b) and blue (c) in (a). (d, e) Difference ratio P between the integrated and central RIXS spectra as a function of the hvin-window (see the definition in the main text). |
