Topology and symmetry analysis of the Sr{sub 2}VO(VO{sub 4}){sub 2} family exhibiting magnetic properties and prediction of structures with different orderings of vanadyl bonds
- Moscow State University, Faculty of Geology (Russian Federation)
A topology and symmetry analysis of structures of the Sr-vanadyl-vanadate family Sr{sub 2}VO(VO{sub 4}){sub 2} with a quasi-one-dimensional spin system, which is responsible for magnetic properties, is performed. Based on the known structure with space group I2/a, structures belonging to its subgroups with ordered vanadyl bonds in octahedra containing the magnetic V{sup +4} ion are derived. Structures with a polar orientation of vanadyl bonds in chains of octahedra correspond to space groups P2{sub 1}/c, P2/c, and Pc, and structures with a nonpolar orientation of vanadyl bonds correspond to space groups P2/a, P2, and P2/n. Variants of disordering of vanadyl bonds over two directions, namely, along the b and a axes, are considered for all structures. The predicted structures can be used for the diagnostics of phases obtained in this family and as initial information necessary for studies of magnetic properties of crystals.
