Letters to the Editor Comment on Acta Phys. Pol. B 32 (2001) 3303 Paper by A.M. Ole? “Magnetic Order in Transition Metal Oxides with Orbital Degrees of Freedom”

摘要

We argue that the ³A₂ state considered by Ole? in Acta Phys. Pol. B 32, 3303 (2001) for the d ² system occurring in the V³⁺ ion in V₂O₃ and LaVO₃ as well as in Ti²⁺ ion in TiO and in many other oxides is wrong. The proper ground state is ³T_1g — its 9-fold degeneracy is further split in a crystal by intra-atomic spin-orbit interactions and lattice distortions.
