中文摘要 | The EPR parameters (zero-field splitting D and g factors g(parallel to), g(perpendicular to)) of Cr3+ in a NaInS2 crystal are calculated from high-order perturbation formulas based on the two spin-orbit coupling parameter model for the EPR parameters of 3d(3) ions in trigonal octahedral sites. In the calculations, both the contribution to EPR parameters from the spin-orbit coupling parameter of the central 3d(3) ion and that of ligands are considered. From the calculations it is found that, to explain reasonably the EPR parameters, the local structure (in particular the local trigonal distortion angle theta) in the vicinity of the Cr3+ impurity is different from the corresponding structure in the host crystal. The change of the local angle theta with temperature is also obtained from the temperature dependence of zero-field splitting. The results are discussed. |
