- Аннотация: The Li diffusion in Li1-xCuSbO4 with lithium deficiency x = 0.02, 0.05, 0.07 and 0.1 was studied by investigation of motional narrowing of the central 7li NMR line in the temperature range from 290 K to 470 K. The activation energy of hopping of lithium ions was determined from the temperature dependence of the NMR linewidth. The dependence of the obtained activation energy on the lithium content indicates the opening of motion channels in the crystals at x close to 0.1 due to the formation of free vacancies at the lithium position, which favors the thermally activated hopping of ions.
