2p3d Resonant Inelastic X-ray Scattering of Cobalt Oxides

Abstract

The cobalt oxides hold plenty of interesting phenomena in the fields of both chemistry and physics because cobalt ions are rich in charge, orbital, and spin degree of freedom. This thesis is focused on the study of cobalt oxides using 2p3d resonant inelastic x-ray scattering (RIXS) to gain more insight into the electronic structure of cobalt oxides. Different aspects of the electronic and magnetic structure of cobalt oxides are discussed, including charge transfer and hybridization effects, the nature of the competing spin states, the support-induced strain effect in thin oxide films, exciton dispersion and mixed valence phenomena.
