Ma. Tanatar, Light interference study of superionic transition in synthetic metal - Solid electrolyte hybrid (BEDT-TTF)(3)AgxI8, MOLEC CRYST, 341, 2000, pp. 1343-1346
First order phase transition at 163-172 K is found in the (BFDT-TTF)(3)AgxI
8 compound in close vicinity to the temperature range of superionic conduct
ivity. This observation indicates formation of the mobile silver ions in th
e salt as a consequence of sublattice melting.
