EXPERIMENTS ON FERMI-LIQUID DOMAINS IN NORMAL AND SUPERFLUID HE-3

We report on pulsed and CW NMR experiments in liquid He-3 at temperatures below 10 mK, when the Fermi liquid interaction gives rise to a nondissipative spin currents. Due to these currents, a coherently precessing spin state may be formed in NMR-experiments with Fermi liquids. The state consists of two domains. In one of the domains the magnetization is oriented along, and in the other opposite to the direction of the magnetic field. Hitherto such a state has only been observed in He-3-He-4 solutions. We have found that the domains can also be formed in normal He-3. Experimental results for normal He-3 are in a good agreement with theory and computer simulations. The conditions necessary for the formation of the state have been determined. We also have found that the two-domain state may be also created in the superfluid state (at least near T-c).
