| Temperature dependence of the b02 spin-hamiltonian parameter for Gd3+ in RbCdF3 single crystals is described. The dependence is interpreted in terms of the 4f7 electrons coupling to the whole phonon spectrum of the crystal. The presented data give also an insight into the dynamics of charge compensators causing a tetragonal distortion of the crystal field. |
