RECENT EXPERIMENTS ON SPIN-POLARIZED LIQUID-HE-3

The importance of spin fluctuations on the physical properties of liqu id He-3 can be probed by studying the polarization dependence of its m agnetic susceptibility and viscosity. We discuss the present state of two such experiments. Using the rapid melting technique to strongly po larize liquid He-3, we have measured the viscosity enhancement induced by the polarization up to unprecedented large polarizations at a low temperature (80 mK). At a polarization of 60%, the enhancement reaches a factor 2.5, comparable to that of the inverse susceptibility at the same polarization.
