چکیده انگلیسی
In this paper, the whole microscopic energy matrix elements of 3d3 and 3d7 within the molecular orbit scheme are obtained. Both the electrostatic parameters, the spin-orbit interaction of the central metal ion and the ligands, the crystal-field potential and the Tress correction, and the spin-spin interaction are considered. By means of the perturbation method, the cubic spin-Hamiltonian parameters g and u are investigated. Results show that the contribution to g due to the spin-spin interaction is negligible. However, the contribution to u due to the spin-spin interaction cannot be neglected. As some illustrations, the 3d7 energy matrix is used to study the cubic electronic paramagnetic resonance experiments of Co2+ in ZnS and ZnSe crystals. The theoretical results agree well with the experimental findings.
