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, g) for 3 d2(8) ions in Al2O3 crystals have been investigated. The results show that the contributions to D, g and g from the spin-orbit interaction are dominant. The contributions from weaker magnetic interactions to D decrease (increase) with increasing charge of impurity ions for 3 d2 (3 d8) ions.
