Abstract
It is shown within the context of simple paramagnon theory that if spin fluctuations are responsible for the pairing in superfluid , then the direction of paired spins in the 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 phase can thus help to test the paramagnon-pairing hypothesis.
