| 中文摘要 | The EPR parameters (g factors g(parallel to), g(perpendicular to) and hyperfine structure constants A(parallel to), A(perpendicular to)) 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 3d(n) ion and that of ligands are considered. It is found that the oxygen octahedron surrounding the 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 |Delta R| = |R-parallel to -R-perpendicular to|) in V4+ center is much greater than the corresponding value in the pure crystal. The cause related to the strong Jahn-Teller effect is discussed. |
