Fig. 5: Ni L3-edge resonant inelastic x-ray scattering (RIXS) of LiNiO2.
From: Temperature-dependent dynamic disproportionation in LiNiO2
a RIXS intensity map measured across the L3-edge at 20 K with maximum intensity in yellow and minimum intensity in black, b energy loss spectra (blue) at incident photon energies (i) 852.5 eV, (ii) 853.5 eV, and (iv) 855.0 eV compared to calculated loss spectra (orange). Calculated spectra were normalized to 85% of the maximum experimental intensity to account for the fluorescence feature (FL). Relative compositions of nickel species (green, purple, pink) were the same as for IPFY (Fig. 3b). Full calculated d-d and charge-transfer intensity maps are shown in Supplementary Fig. 7.
