✦ Synopsis

Concentration of nn-dipoles, nnn-dipoles and charge carriers as well as parameters related to their reorientation and mobility have been estimated from an analysis of ax. conductivity data of polycrystalline samples of the Sr,~,ThxF,+,x solid solution. The molar fraction of charge carriers has been evaluated as a function of composition. Results obtained confirm, in agreement with the clustering process model, that the (Fi), ions responsible for long range motions in Sr, -,Th,F2+2x are interstitial fluoride ions of F"' type.
