Kavun, A. Slobodyuk, S. Gnedenkov, S. Sinebryukhov, V. Goncharuk, N. Uvarov, V. Sergienko] NMR (19F, 207Pb) and impedance spectroscopy methods are used to investigate the ionic mobility and conductivity in solid solutions of (1 − x)PbF2 − xMF3 (where M is Y3+ and La3+) at 0.05 ≤ x ≤ 0.1. The factors determining the form of ionic movement in these systems and its energy in a range of temperatures from 170 K to 500 K are considered and analyzed. It is found that the solid solutions studied can be related to the class of superionic conductors: their σ value is 2·10−3 − 5·10−3 S/cm at temperatures above 470 K, and the activation energy does not exceed 0.52-0.58 eV.
