Abstract
We study the influence of disorder on the magnetic properties of the :groun d state for restricted geometries. We find that for two-dimensional systems disorder enhances the spin polarization of the system. The tendency of dis order to enhance magnetism in the ground state may be relevant:td recent ex perimental observations of Spin polarized ground states in quantum dots and small metal gains.
