Direction of Paired Spins in the A sub 1 Phase of He3: A Test of the Paramagnon Induced Pairing Hypothesis.

摘要

It is shown within the context of simple paramagnon theory that if spin fluctions are responsible for the pairing in superfluid 3He, then the direction of paired spins in the A1 phase should be opposite to that of the field-induced magnetization in the normal state, in contradiction to predictions made using weak-coupling theory. Measurements of the direction of paired spins in the A1 phase can thus help to test the paramagnon-pairing hypothesis. (Author)
