Crystal and magnetic structures of mixed-valent V2OPO4

Abstract: The electronic states of transition metal oxides usually result from a coupling between the three degrees of freedom: charge, orbital and spin states. When metal-metal distances are short, direct bonding interactions between M ions having localised t2g orbital order can give rise to more complex quantum electronic states called ‘orbital molecules’ [1]. They appear as cation site distortions coupled through their orbital ordering and sharing of electron density, and could have applications in orbitronics. Mixed valent transition metal oxides with face- or edge-shared octahedra are good candidates to display such phenomena. As part of an ERC grant, we are hunting for new examples of compounds with orbital molecules. A variable temperature neutron diffraction study is needed to determine the magnetic structure and to study the structural transition of V2OPO4.
