抄録

A repulsive interaction model for superconductivity (SC) in fullerides is studied using a second-order perturbation theory with respect to Coulomb repulsion. With the purely repulsive interaction, Tg and E g pairs are the most stable in bcc and fcc lattices, respectively. In addition to anisotropic SC pairs, the s-wave (Ag) pair can also be formed in both lattice models. Multiple Fermi surfaces in fullerides stabilize the Ag pairs. We propose that the cooperation between Coulomb repulsion and electron-phonon interaction is responsible for the high T c
