摘要	The electron paramagnetic resonance g factors g(parallel to) and g(perpendicular to) for Er3+ in the superconductor Pr2CuO4 are investigated by using the perturbation formulas of g factors for a 4f(11) ion in tetragonal symmetry. In these formulas, the contributions to the g factors due to the second-order perturbation terms and the admixture of different states are considered. The crystal field parameters used in the calculations are obtained from the superposition model and the local structural parameters of the impurity Er3+ located on the host Pr3+ site. The superposition model parameters adopted in this paper are comparable with those for similar tetragonal Er3+ centers in some zircon compounds in previous work. The above investigations may be helpful to understand the electronic and magnetic properties and hence the superconductivity of the Er3+ doped Pr2CuO4.
