Three fundamentally different electronic structures for 3d electron states in LaCoO3, discussed in the current literature, have been presented. We are in favour of the localized electron atomic- like approach that yields the discrete energy…

We have attributed magnetism and electronic structure of V2O3 to the V3+ ions. We claim that the V3+ ion in V2O3 should be considered as described by the quantum numbers S=1 and L=3. Such quantum numbers result from two Hund's rules. The…

We argue that in LaCoO3 exists the fine electronic structure associated with the atomic-like states of the Co3+ ions and caused by the crystal-field and intra-atomic spin-orbit interactions. This low-energy fine electronic structure has to…
