| 中文摘要 | The complete high-order perturbation formulas based on a two-mechanism model for the spin-Hamiltonian (SH) parameters (g-factors g(parallel to), g(perpendicular to), and zero-field splitting D) of 3d(3) ions in trigonal octahedral sites are derived. In the model, not only the conventional contribution to SH parameters from the crystal-field (CF) mechanism, but also that from the charge-transfer (CT) mechanism (which is omitted in the CF theory) are included. From these formulas, the SH parameters of Mn4+ replacing Al3+ in Al2O3 crystal are calculated by using the parameters related to the optical spectral data and the defect structure of the studied system. The results (including the relative importance of the CT mechanism on the SH parameters and the defect structure of Mn4+ impurity center) are discussed. (C) 2008 WILEY-VCH Verlag GmbH & Co.
