Title: Orbitally Degenerate Spin-1 Model for Insulating V{sub 2}O{sub 3}

Abstract

Motivated by recent neutron, x-ray absorption, and resonant scattering experiments, we revisit the electronic structure of V{sub 2}O {sub 3} . We propose a model in which S=1 V{sup 3+} ions are coupled in the vertical V-V pairs forming twofold orbitally degenerate configurations with S=2 . Ferro-orbital ordering of the V-V pairs gives a description which is consistent with all experiments in the antiferromagnetic insulating phase. (c) 2000 The American Physical Society.
