Crystal field and microscopic spin Hamiltonians approach including spin–spin and spin–other-orbit interactions for d2 and d8 ions at low symmetry C3 symmetry sites: V3+ in Al2O3
TL;DR: In this paper, a new module has been developed within the CFA/MSH computer package, which is applicable for d2 and d8 ions at sites of trigonal symmetry type I (C3v, D3,D3d), including the ‘imaginary’ CF term.
Journal ArticleDOI
Ligand field analysis of the 3dN ions at orthorhombic or higher symmetry sites
Yau Yuen Yeung,Czesław Rudowicz +1 more
TL;DR: A computer package has been developed to calculate the energy levels and the ligand field states for a full Hamiltonian including the electrostatic terms, Trees correction, the spin-orbit interaction and theligand field interactions within the 3dN configuration.
Journal ArticleDOI
Microscopic spin Hamiltonian approaches for 3d8 and 3d2 ions in a trigonal crystal field - perturbation theory methods versus complete diagonalization methods
TL;DR: In this paper, a new microscopic spin Hamiltonian (MSH) approach is presented and a CFA/MSH computer package based on our crystal-field analysis (CFA) package for 3dN ions is developed for numerical calculations.

Journal ArticleDOI
Microscopic spin-Hamiltonian parameters and crystal field energy levels for the low C3 symmetry Ni2+ centre in LiNbO3 crystals
TL;DR: In this paper, the microscopic spin Hamiltonian (MSH) parameters and crystal field (CF) energy levels for Ni2+ ions in LiNbO3 crystals were investigated using the crystal field analysis/microscopic spin-Hamiltonian package recently developed.
