| 英文摘要 | Motivated by the recent neutron-diffraction experiment on YVO3, we consider a microscopic model where each V3+ ion is occupied by two 3d electrons of parallel spins with twofold-degenerate orbital configurations. The mean-field classical solutions of the spin-orbital superexchange model predicts an antiferro-orbital ordering at a higher temperature followed by a C-type antiferromagnetic spin ordering at a lower temperature. Our results are qualitatively consistent with the observed orbital phase transition at similar to200 K and the spin phase transition at similar to114 K in YVO3. |
