Magnetic phase diagram in a three-dimensional electron gas

Abstract The ground state of a three-dimensional electron gas with intermediate electron density is investigated within a framework of the local spin density approximation (LSDA). Several types of exchange-correlation energy are applied to the LSDA. The ground state shows a magnetic transition from a nonmagnetic fluid to a spin-fully polarized ferromagnetic Wigner film except a few types, for which spin-partially polarized ferromagnetic fluid and Wigner film are found in a narrow range of electron density.
