摘要
By considering weaker magnetic interactions (including spin-spin and spin other-orbit interactions) in Hamiltonian, the spin-Hamiltonian parameters, including the zero-field splitting parameter D and g factors (g(parallel to), g(perpendicular to)) for 3d(2(8)) ions in Al2O3 crystals have been investigated. The results show that the contributions to D, g(parallel to) and g(perpendicular to) from the spin-orbit interaction are dominant. The contributions from weaker magnetic interactions to D decrease (increase) with increasing charge of impurity ions for 3d(2) (3d(8)) ions.
