Spin-Hamiltonian Parameters For Cr Li 3+ Doped In LiNbO 3

Abstract By using crystal field theory, the spin-Hamiltonian parameters [zero-field splitting D, the giromagnetic factors g ( g || and g ⊥ ) and the first excited state splitting δ ( 2 E )] for the Cr Li 3+ doped in LiNbO 3 have been calculated from the higher-order perturbation formulas. The method...

Description
Summary:Abstract By using crystal field theory, the spin-Hamiltonian parameters [zero-field splitting D, the giromagnetic factors g ( g || and g ⊥ ) and the first excited state splitting δ ( 2 E )] for the Cr Li 3+ doped in LiNbO 3 have been calculated from the higher-order perturbation formulas. The method used is based on the two-spin-orbit coupling parameter model, in a cluster approach. The g parameters were also calculated as a second derivative of the energy, method implemented into ORCA computer program. The results were discussed and good agreement with experimental data was demonstrated.
