Investigation on Spin Hamiltonian Parameters for Tetragonal Ytterbium Center in Lutetium Orthovanadate
Rare earth doped orthovanadate crystal LuVO<,4>: Yb <3+> shows high power laser applications because of the low quantum defect and the high thermal conductivity. Since electronic paramagnetic resonance (EPR) is a powerful tool to analyze the electronic properties and the local structures of paramagnetic impurity centers in crystals, the EPR spectra of the Yb<3+> centers in LuVO<,4> crystal were measured recently. However, the above experimental results have not been theoretically interpreted. In this work, The EPR g factors and the hyperfine structure constants of <171>Yb<3+> and <173>Yb<3+> isotopes in LuVO<,4> crystal were theoretically studied from the perturbation formulae of the spin Hamiltonian parameters for 4f<13> ion in tetragonal symmetry. The needed crystal parameters were obtained from the superposition model and the local structure of the studied system. The calculated results were in reasonable agreement with the observed values.
