MAGNETIC-RELAXATION OF SOLID AND LIQUID-HE-3 CONFINED INSIDE A SILVERSINTER

We present T-1 measurements performed in liquid and solid He-3 confine d in sintered silver. In the liquid case, we find a close to linear re lationship between T-1 and the applied magnetic field, similar to othe r (non metallic) systems, and up to higher frequencies (corresponding to 11 T) than previously reported. In the solid, the relaxation rate i s found to increase spectacularly at large polarizations, which may in dicate a polarization dependence of the exchange motion.
