In the full lower band case, strong anti-ferromagnetic correlations develop when the on-site repulsive interaction strength $U$ becomes comparable to the quasi-particle band width. In the three-quarters full case, a novel kind of spin correlation develops that is consistent with the resonance between a $(\\pi,0)$ and a $(0,\\pi)$ spin-density wave. In this state the spins on different sublattices appear uncorrelated.
