An 19F source NMR investigation of the Pb1−xMgxF2 solid solution is undertaken as a function of temperature. Several F− ion sublattices are identified, they become progressively mobile on the NMR time scale at increasing temperature. Clusters are proposed from the composition dependence of the anionic distribution determined by deconvolution of the low temperature 19F source NMR spectra. Temperature dependence of the jump frequency shows the existence of several F− ion motions corresponding to exchange motions inside and between fluoride sublattices.< Leer menos
