Abstract
The static magnetic susceptibility of the disordered Hubbard model for the half-filled-band case is studied using exact eigenstates of the noninteracting disordered system. The macroscopic renormalization-group method is applied to study the critical behavior in the vicinity of the noninteracting (Anderson) fixed point. A weak Hubbard interaction is found to stabilize the metallic phase.Keywords
