Spin-Spin and Spin-Other-Orbit Interactions of Spin-Hamiltonian Parameters for 3d²⁽⁸⁾Ions in Al₂O₃Crystals

Abstract

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 3d 2(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 3d 2 (3d 8 ) ions.
