Abstract
On the basis of the three-dimensional Hubbard model, the superconducting (SC) mechanism ofCeIn3under high pressure is investigated by means of third-orderperturbation theory with respect to the on-site Coulomb interactionU.Here we propose a d-wave pairing state induced by antiferromagneticspin fluctuations. The estimated SC transition temperature is lower byone order than that in the two-dimensional system for the same value ofU/W (W = bandwidth).This result is consistent with the difference between CeIn3 andCeRhIn5.
