摘要	The local release factors k(1), which are introduced to stand for the release or elongation effect of the impurity-ligand bond along the C-4-axis at the cubic-tetragonal phase transition, are studied by analyzing the EPR zero-field splitting for Cr3+ and Ni2+ ions in RbCdF3 crystals. The results are compared with those of other paramagnetic ions in RbCdF3 and in the similar crystal RbCaF3. It is found that for the same crystal, the factor k(1) is different from impurity to impurity and that for the same impurity, the factors k(1) in both RbCdF3 and RbCaF3 crystals are close to each other. The cause of the very small zero-field splitting for Cr3+ in the tetragonal phase of RbCdF3 crystal is suggested. (C) 2004 Elsevier B.V.
