Abstract
We make use of the Hubbard model to investigate the conditions for the existence and the stability of a spin-density wave in a system with a chemically induced charge-density wave. We And that the transition be tween the paramagnetic and the antiferromagnetic ground state is disco ntinuous both in the weak-coupling and strong-coupling regimes.
