The EPR parameters (g factors g||, g⊥ and hyperfine structure constants A||, A⊥) of V4+ ion in the tetragonal phase of SrTiO3 crystal were studied by high-order perturbation formulas based on a two-spin-orbit-parameter model, where the contributions from the spin-orbit-coupling-parameter of central 3dn ion and that of ligands are considered. It is found that the oxygen octahedron surroundingthe impurity ion V4+ changes from elongation along the tetragonal axis in the pure crystal to compression and the magnitude of tetragonal distortion of oxygen octahedron (characterized by |ΔR|=|R||−R⊥|) inV4+ center is much greater than the corresponding value in the pure crystal. The cause related to the strong Jahn-Teller effect is discussed.
