F-19 NMR investigation of the K3InF6 ternary fluoride
The study of electrical properties of K3InF6, which offers four allotropic forms has shown that the higher-temperature transition at T-C is of ionic-superionic type. An F-19 NMR spectroscopy investigation has been undertaken in order to determine the diffusion processes in this material. The F- ion diffusion properties have been correlated with the structural and electrical properties.
