Abstract
We study the interplay of antiferromagnetic and superconducting orders in a two-dimensional Hubbard model with on-site repulsion and nearest-neighbor attractive interaction. This type of interaction has been widely used to model d-wave superconductivity. Our mean-field calculations indicate that such an attractive interaction enhances the staggered magnetization produced by the on-site repulsion. As a result, superconductivity is strongly suppressed. Stripe formation is also affected.
