  Do electrons become ferromagnetic just because of their repulisve Coulomb
interaction? Our calculations on the three-dimensional electron gas imply that
itinerant ferromagnetim of delocalized electrons without lattice and band
structure, the most basic model considered by Stoner, is suppressed due to
many-body correlations as speculated already by Wigner, and a possible
ferromagnetic transition lowering the density is precluded by the formation of
the Wigner crystal.
