A series of experiments was carried out on very dilute [sup 3]He-[sup 4]He mixtures and on pure [sup 3]He liquid at very high field/temperature ratios (H [le] 8, T, T [ge] 4.3mK). In this regime these systems display a strong Leggett-Rice effect, weakly damped paramagnetic spin waves, and significant polarization effects on spin and momentum transport. The dilute mixture experiments used NMR to observe standing spin waves, and vibrating-wire viscometry to measure momentum transport. A very satisfactory agreement is found with the recent kinetic-equation calculations of Jeon and Mullin [Phys. Rev. Lett. 62, 2691 (1989)]. The pure [sup 3]He experiments may provide the first evidence for field-induced relaxation of transverse spin currents.
