Abstract
Completely polarized 3He behaves in many respects very differently from normal 3He. In principle it can be obtained by purely thermodynamical methods, starting from a strongly polarized solid (by a magnetic field at very low temperature), as long as the overall experimental time is less than T1, the magnetic relaxation time. We discuss the crucial points of such an experiment — dependence of liquid 3He energy on magnetization, value of T1 — and the new experimental possibilities it opens. In particular completely polarized 3He appears as the best chance to observe a vacancy solid phase, first described by A. Andreev and I. M. LifshitzKeywords
