摘要：

On the basis of the three-dimensional Hubbard model, the superconducting (SC) mechanism of CeIn3 under high pressure is investigated by means of third-order perturbation theory with respect to the on-site Coulomb interaction U. Here we propose a d-wave pairing state induced by antiferromagnetic spin fluctuations. The estimated SC transition temperature is lower by one order than that in the two-dimensional system for the same value of U/W (W = bandwidth). This result is consistent with the difference between CeIn3 and CeRhIn5.
