Abstract

The superconductivity of fulleride is driven dominant by the electron-intramolecular-phonon interaction and, this interaction leads to a local pairing of electrons. The purpose of the present paper is to discuss the influences of the phase fluctuations of these local pairs on the superconductivity. A phenomenological model, which regards the fulleride as a superconducting network, is used. It is shown that the influences are to suppress both the magnitude of superconducting order parameter and the critical temperature, particularly to change the characteristic of the normal-superconducting transition, in which the order parameter does not continuously turn to zero but rather jumps from a finite value to zero.
