Abstract

We investigated the electrical conductivity of alkali fullerides K₃C₆₀ and (NH₃)_xNaRb₂C₆₀ by the microwave cavity perturbation method. We found that the resistivity of (NH₃)_xNaRb₂C₆₀ is rather metallic both for x = 0.8 and x = 0.9. These results suggest that the disappearance of superconductivity in (NH₃)K₃C₆₀ is due to the distortion of the crystal structure from the cubic structure. This also suggests that superconductivity of alkali-doped fullerides can appear only in the cubic structure.
