Normal Helium 3: A Mott–Stoner Liquid

Abstract
A qualitative picture of normal 3 He is proposed, which brings together the concept of an "almost localized" liquid and the existence of ferromagnetic spin correlations. The range of these correlations is shorter than in paramagnon theory, and the spin fluctuations are never in the critical regime within our approach, even at high pressure. A lattice model is introduced, which illustrates this physical picture. We also demonstrate that a metamagnetic transition in the field-dependent magnetization is not a necessary consequence of a quasilocalized picture.
