摘要：

The spin-Hamiltonian parameters b(2)(2), b(2)(-1) and b(2)(0) for Gd3+-O2- center in the tetragonal phase of Rb0.95K0.05CaF3 perovskite-type compound are studied by the superposition model which considers the (GdOF5)(4-) octahedron distortion related to the elongation or release of the metal-ligand bond lengths in the octahedron. The parameters b(2)(m) can be reasonably explained, and information for the local phase transition behaviour is obtained.
