Abstract
The Kondo lattice model enlarged by an antiferromagnetic coupling JAF between the localized spins is
here investigated using computational techniques. Our results suggest the existence of a d-wave superconducting
phase close to half-filling mediated by antiferromagnetic fluctuations. This establishes a closer
connection between theory and heavy fermion experiments than currently provided by the standard Kondo
lattice model with JAF 0.
