Abstract
A qualitative picture of normal He-3 is proposed, which brings togethe r the concept of an ''almost localized'' liquid and the existence of f erromagnetic spin correlations. The range of these correlations is sho rter than in paramagnon theory, and the spin fluctuations are never in the critical regime within our approach, even at high pressure. A lat tice 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 pict ure.
