Abstract:

ENDOR experimental spectra of Gd3+ tetragonal impurity centers in CaF2 and SrF2 crystals were used to determine the superhyperfine interaction (SHFI) constants of the impurity with F-19 nuclear spins of its first coordination sphere and the compensator ion. The distances in the Cd3+F9- complex were estimated within the model of isotropic SHFI constants suggested in {[}1]. An analysis of the data on the SHFI and spin-Hamiltonian constants {[}2] in terms of the superposition model indicates significant changes in the contributions (due to the Gd3+ mixed states) to these parameters for the tetragonal centers in comparison with the corresponding contributions for the cubic and trigonal centers in the same crystals.
