Evidence for Viscosity Reduction in Moderately Spin-PolarizedHe3

Abstract
By use of the technique of rapidly melting moderately spin-polarized solid He3, the viscosity of transiently produced spin-polarized liquid has been investigated. Partial melting makes a 10% polarized liquid near 50 mK with a viscosity decreased by 25% from the 8-T equilibrium value. Complete melting produces a liquid near 320 mK which shows no comparable polarization effect. These observations support a class of microscopic models in which the liquid is "nearly localized."
