We report on the observation of orbital excitations in YVO3 by means of resonant inelastic x-ray scattering (RIXS) at energies across the vanadium L-3 and oxygen K absorption edges. At the V L3 edge, we are able to resolve the full spectrum of orbital excitations up to 5 eV. In order to unravel the effect of superexchange interactions and the crystal field on the orbital excitations, we analyzed the energy and temperature dependence of the intra-t(2g) excitations at 0.1-0.2 eV in detail. While…

Effects of rare-earth size on the electronic structure of La 1 −
The electronic structure of La1−xLuxVO3(x = 0, 0.2, 0.6 and 1) single crystals has been investigated using soft x-ray absorption spectroscopy, soft x-ray emission spectroscopy, and resonant soft
Effects of rare-earth size on the electronic structure of La1−xLuxVO3
The dd* transitions of the mixed compounds are noticeably suppressed with respect to those of the pure compounds, possibly owing to the formation of C-type orbital ordering induced by large R-site size variances.
Spin-orbit coupling and crystal-field splitting in Ti-doped Ca2RuO4 studied by ellipsometry
In Ca 2 RuO 4 , the competition of spin-orbit coupling ζ and tetragonal crystal field splitting ∆ CF has been discussed controversially for many years. The orbital occupation depends on ∆ CF /ζ ,
High-resolution resonant inelastic x-ray scattering study of the electron-phonon coupling in honeycomb α−Li2IrO3
The excitations in honeycomb $\alpha$-Li$_2$IrO$_3$ have been investigated with high-resolution resonant inelastic x-ray scattering (RIXS) at the O K edge. The low-energy response is dominated by a

Resonant inelastic x-ray scattering study of bond order and spin excitations in nickelate thin-film structures
The rare-earth nickelates ($R$NiO${}_{3}$) have been subject to intense investigation, mostly because of their rich phase diagrams, comprising a sharp temperature-driven metal-to-insulator transition
