Scientific paper

The Hubbard model on the fcc lattice is studied in the limit of infinite spatial dimensions. At sufficiently strong interaction finite temperature Quantum Monte Carlo calculations yield a second order phase transition to a highly polarized ferromagnetic state. Ferromagnetism is stable over a wide hole doping regime but not for electron doping. A possible non-Fermi liquid behavior is discussed.
