摘要 | The high-order perturbation formulas for the zero-field splitting parameters D and E, and g factor g(x), g(y), g(z) for 3d(3) ions in rhombic symmetry are derived by using a two spin-orbit coupling parameter model, in which both the contributions from the spin-orbit coupling of central d(3) ion and that of the ligands are considered. From these formulas, spin Hamiltonian parameters for the rhombic defect centers Cr3+-Li+ and Cr3+-Na+ in Cs2CdC4, crystals are calculated by considering the suitable defect-induced lattice distortions. The results agree well with the observed values. The contributions to spin Hamiltonian parameters from the spin-orbit coupling of ligands are discussed. (C) 1999 Elsevier Science B.V.
