The Eu

The EPR-parameters of Eu2+ substituted for Cd2+ in CdF2 have been measured at 300, 77 and 1,5°K. They are summarized in Table 1. The EPR spectrum is that of an S-state-ion in a cubic environment. As with Eu2+ inCaF2, SrF2 or BaF2 there is in CdF2 a superhyperfine (SHF) -interaction between the Eu2+- and F–-ions, which results mostly in an inhomogeneous broadening of the lines but sometimes in CdF2 in a splitting. There are some indications that the point charge model is not fully correct and that a slight deviation from the cubic environment does exist.

The magnitude of the valence force constants is discussed in terms of the polarization of the static electron distribution.
