Description

Relaxation times for 19F nuclei and electric conductivity in Rb2TiF6 and Cs2TiF6 polycrystals are measured. The parameters of reoriented anion motion and diffusion cation motion are determined according to the NMR data. The effect of phase transition to the cubic phase on the parameters of these motions are studied. High conductivity reaching values σ∼10-2-10-3 Ohm-1xm-1 is detected at high temperatures. The electric conductivity observed is shown to be caused by the diffusion motion of Rb+ and Cs+ cations
