Abstract

The electron spin resonance of MoO^3-₄ in YVO₄ was studied at 4.2K. The Mo⁵⁺ has a d_xy ground state and is shown to move off the V⁵⁺ substitutional site of D_2d symmetry to one of four crystallographically equivalent off-center sites of C₂ symmetry, located in the 〈110〉 direction. The Mo⁵⁺ spectrum is compared to Cr⁵⁺ in YVO₄ and YPO₄ and V⁴⁺ in ZrSiO₄ and other zircon-like crystals which show dynamic effects that we interpret as tunneling or thermally activated hopping between off-center sites.
