Abstract
We report measurements of the nuclear magnetization of submonolayer li quid He-3 films adsorbed on a graphite substrate (Papyex) preplated by a monolayer of He-4. In the submilliKelvin temperature range we obser ve a substantial enhancement of the nuclear magnetization with respect to the degenerate Fermi Liquid value. The unusual temperature depende nce of this new contribution to the liquid 3He film magnetization agre es well with that expected from the theory of weal disorder in two-dim ensional (2D) correlated Fermion systems. The effects of disorder and reduced dimensionality suppress the superfluid transition at least to below 180 mu K.
