EFFECT OF MAGNETIC SCATTERING ON THE HE-3 SUPERFLUID STATE IN AEROGEL

Pure He-3 in highly porous aerogel forms an equal-spin pairing superfl uid with transition temperatures suppressed from bulk values. We have measured the magnetic field dependence of the transition temperature f rom which it can be inferred that both magnetic and nonmagnetic quasip article scattering from solid He-3 at the aerogel surface is important to the superfluid state. Replacement of the solid He-3 on the surface of the aerogel with He-4 gives rise to a unequal spin pairing superfl uid phase.
