| 中文摘要 | The spin-Hamiltonian parameters (g factors, [image omitted], [image omitted], and hyperfine structure constants, [image omitted], [image omitted]) for Yb3+ at the 12-fold coordinated Sr2+ site of tetragonal SrTiO3 crystal at T approximate to 2 and 50 K were calculated using the completed diagonalization (of the energy matrix) method (CDM). Differing from the conventional CDM, the Hamiltonian concerning the energy matrix in this CDM contains the Zeeman and hyperfine interaction terms and so the spin-Hamiltonian parameters can be calculated directly from CDM. The crystal parameters used in the energy matrix are calculated from the superposition model, in which the tetragonal distortions and hence the order parameters phi at both temperatures are applied. From the calculations, the spin-Hamiltonian parameters at both temperatures are explained reasonably and the signs of hyperfine structure constants for the 171Yb3+ and 173Yb3+ isotopes in SrTiO3 are suggested. The results are discussed. |
