| Abstract: | Raman measurements of the superionic conductor KAg4I5 are reported between 77K and 296K and compared to similar data of RbAg4I5. The mode frequencies for the two materials are very similar and a mode at 22.7 cm?1 abruptly and reversibly disappears at the transition temperature, Tc=137 K, as is observed in RbAg4I5, at 121 K. |
