英文摘要	Low-energy orbital excitations in spinel FeCr2S4 have been studied element specifically at both Fe and Cr 2p-3d resonances by resonant inelastic X-ray scattering (RIXS). As a first step X-ray absorption spectroscopy measurements confirmed that iron, located at the tetrahedral (T-d) sites of the spinel structure, is in a Fe2+ (d(6)) state and chromium, located at the octahedral (O-h) sites, is in a Cr3+ (d(3)) state. We have identified RIXS spectral features with the help of crystal-field simulations that account consistently for on-site dd excitations and provide 10Dq = 0.30 +/- 0.05 eV for Fe T-d sites and 10Dq = 1.60 +/- 0.05 eV for Cr Oh sites. The giant magneto-optical Kerr effect previously observed for photons with 0.3 eV can be unambiguously attributed to the lowest possible dd excitations on the iron site Fe(e(3)t(2)(3)) -> Fe(e(2)t(2)(4)). A 1.6 eV energy-loss feature, measured in the Fe 2p-3d RDCS spectra, is found to be a two-site orbital excitation directly related to superexchange (SE) interaction between Fe and Cr cations. It opens new perspectives for applying RIXS to study SE in a broad range of 3d transition metal compounds.
