Abstract
First principles spin-polarized electronic band structure calculations were carried out for three ordered spin states of CdVO 3, and the strengths of its corner- and edge-sharing spin exchange interactions were estimated. To gain insight into why CdVO 3 exhibits ferromagnetism while CaV 2O 5 does not despite their apparent structural similarity, the spin exchange interactions of CdVO 3 and CaV 2O 5 were compared in terms of spin dimer analysis using extended Hückel tight binding calculations, and the local geometries of their V 4+ ions were examined.
