抄録

We studied the orbital ordering of spinel vanadate, MnV2O4. It was found that this compound exhibits a structural phase transition from cubic to tetragonal and ferrimagnetic ordering simultaneously at 57 K, and the structural transition temperature can be varied by applied magnetic field, giving rise to a magnetic-field-induced structural phase transition. We obtained the evidence of antiferro-orbital ordering in the tetragonal phase by X-ray diffraction measurement on the single crystal. This simultaneous spin and orbital ordering can be explained by the coupling between spin and orbital degrees of freedom, called Kugel-Khomkii interaction.
