Description
The U = ∞ limit of the Hubbard model is studied using a variational approach in which the spins are in a static coherent state. We find that the Nagaoka Ferromagnetic state is no longer the ground state as soon as two holes are presented, and this for various geometries. We suggest that this instability also remains for a finite density of holes. (author). 13 refs
