The polarization and density dependence of the enhanced spin susceptibility χ∼m*g* in a 2DES in GaAs/AlGaAs over a wide range of low densities. The analysis provides an explanation for the anomalous g factors reported recently in GaAs 2DeS and 2DHG. The susceptibility χ of the paramagnetic Fermi liquid increases with decreasing density, inqualitative agreement with recent QMC calculations.
