Abstract

Electron energy loss spectroscopy installed in a transmission electron microscope was used to investigate the electronic states of LiMnVO₄. The Mn-L multiplet structure of LiMnVO₄ and the typical manganese oxides clearly revealed that the manganese in LiMnVO₄ is divalent. The V-L spectrum showed a characteristic multiplet structure in tetrahedrally coordinated-d⁰ oxides, revealing that vanadium is pentavalent. The O-K spectrum was compared to that of LiMnPO₄, and showed that the lowest unoccupied states of LiMnVO₄ have mainly vanadium 3d character and that the bonding between vanadium and oxygen in LiMnVO₄ is more ionic than phosphorus and oxygen in LiMnPO₄.
