O. Dankert et al., EPR STUDY OF CONCENTRATION-DEPENDENCE IN CE, CE-LA AND CE-Y DOPED SRF2, Radiation effects and defects in solids, 135(1-4), 1995, pp. 667-670
Experimental results of an EPR-study of the concentration dependence o
f the doubly integrated intensity and linewidth of the signals associa
ted with tetragonal Ce3+-F--dipoles in Sr1-xCexF2+x, Sr-1-0.005-x Ce0.
005LaxF2+0.005+x and Sr-1-0.005-x Ce0.005YxF2+0.005+x are presented. B
oth show a nonlinear behaviour. Besides the tetragonal defects no othe
r symmetries have been found.
