| 中文摘要 | The electron paramagnetic resonance (EPR) parameters (g factors and the hyperfine structure constants) for Ni(2+) and Co(+) in MgO are theoretically studied from the perturbation formulas of these parameters for a 3d(8) ion in octahedral crystal-fields. In the computations, the ligand orbital and spin-orbit coupling contributions are taken into account using the Cluster approach. The calculated EPR parameters are in good agreement with the experimental data. The larger g factor and the smaller magnitude of the hyperfine structure constant for Ni(2+) as compared with those for Co(+) can be attributed to the higher spin-orbit coupling coefficient and the lower dipolar hyperfine structure parameter of the former, respectively. |
