Abstract:

The constants of the superhyperfine interaction of Gd3+ with the F-19 nuclear spins in the first four coordination shells were determined from the ENDOR spectra of a trigonal BaF2 : Gd3+ center. These data were used for analysis of the crystalline lattice distortions in the vicinity of the impurity ion. It was found that the largest displacements of fluorine nuclei occurred in the vicinity of the ion compensator and the impurity ion. To calculate the anion positions within the first coordinate shell, whose electron-nuclear interaction with Gd3+ depends considerably on chemical bonds in the Gd3+F8- complex, an empirical model is used for the isotropic constants of the superhyperfine interaction of Gd3+ with fluorine nuclei in cubic centers, with allowance made for the impurity ion polarization.
