1. Nuclear magnetic resonance in superionics conductors with fluorite-type structure. / Ressonância magnética nuclear em condutores superiônicos de estrutura fluorita.
The 19F NMR relaxation times T1 and T2 were measured is ternary and nonstoichiometric compounds with the fluorite-type structure. We have studied the Na0.4Y0.6F2.2 crystal in the temperature range 600K to 900K, where the crystal hás not the fluorite structure. The T1 values were measured in two Larmor frequencies: 20.42 MHz and 34.24 MHz. The results for T1
