摘要：

We investigate the interplay between antiferromagnetism and superconductivity for singlet Cooper pairs in a simple cubic lattice. The Landau expansion of the antiferromagnetic part in the free energy is made up to the fourth order of magnetic order parameters. The coupling term between antiferromagnetism and superconductivity in the free energy is investigated with the generalized spin susceptibility (the generalized Yosida function).
