Conference paper


The temperaature and hydrostatic dependences of the cubic EPR spectrum for Gd3+ in RbCaF3, has been investigated. It was found that the metal-ligand destance dependence of the b0 4 parameter can be described by the function type b0 4 ~ rR with k = -20. It was also found that vibronic effects contribute oominantly to the observed temperature dependence of b0 4.
