摘要	The spin Hamiltonian parameters, g parallel to factorsgkand g perpendicular to for Nd3+ in ThGeO4 are theoretically investigated from the perturbation formulas of the g factors for a 4f(3) ion in tetragonal symmetry. In these formulas, the contributions to the g factors from the second-order perturbation terms and the admixture of various states are taken into account. It is found that the calculated g factors of this work are smaller than the experimental results, but close to those in the previous theoretical studies by Gutowska et al. Moreover, the calculated hyperfine structure constants A parallel to and A perpendicular to as well as the energies of the I-4(9/2) Stark levels in this work are also consistent with those in the previous investigations.The discrepancy between theoretical and experimental g factors is discussed.; The spin Hamiltonian parameters, g parallel to factorsgkand g perpendicular to for Nd3+ in ThGeO4 are theoretically investigated from the perturbation formulas of the g factors for a 4f(3) ion in tetragonal symmetry.
