| 摘要 | By means of the resonance theory related to the low-spin 2T2 term for strong field d5 configuration in tetragonal symmetry, the spin-Hamiltonian parameters, g factors g|, g and hyperfine structure constants 191A|, 191A, 193A| and 193A, for two tetragonal Ir4+ centers T and T' in MgO and CaO crystals are calculated. The calculated results are in reasonable agreement with the experimental values. From the calculations, negative signs are suggested for the hyperfine structure constants A|, A, the defect models for the two tetragonal Ir4+ centers suggested in the earlier paper are confirmed and the defect structural data for both centers in MgO and CaO crystals are obtained. These results are discussed. |
