摘要：
The experimentally observed amazing dependence of a critical magnetic field B, of a full field-induced spin polarization and a spin susceptibility chi(*) of a two-dimensional electron gas on the electron density can be explained by screening of the Coulomb potential. The possibility of spontaneous full spin polarization expected at lower electron densities also crucially depends on screening. (C) 2003 Elsevier B.V. All rights reserved.
