Abstract
NMR and impedance spectroscopy are used to study the ionic mobility and conductivity in crystalline samples in PbSnF4-MF systems (M = Li, Na, K) in a 150-473 K temperature range. The 19F NMR spectral parameters, types of ionic motion, and ionic conductivity value in the PbSnF4 compound doped with alkali metal fluoride is found to be determined by the temperature, nature, and concentration of an alkali cation. The specific conductivity of the crystalline samples in PbSnF4-MF systems (M = Li, Na, K) is rather high at room temperature and hence, it seems possible to apply them in the development of functional materials with high ionic (superionic) conductivity
