摘要：

The available data on ligand hyperfine interactions for Gd3+ and Eu2+ in alkaline-earth fluorides is interpreted using a model in which the covalent contributions of s and p electrons on the ligands are assumed to follow a power-law dependence upon the ligand distance R. Electrostatic polarisation of the ligands, caused both by extra charge on the paramagnetic ion and by distortion of the lattice, produces a large contribution to the ligand hyperfine interaction parameters. A crude theoretical model is developed which indicates a similar magnitude of electrostatic contribution.
