Abstract
We have observed spin waves in dilute 3 He, spin polarized by a 4 He circulating dilution refrigerator. The maximum polarization is a factor 5 higher than the equilibrium polarization in the magnetic field of 10.54 T at temperatures between 10 and 20 mK. The measured spin wave damping is about a factor 4 lower than the damping expected from previous spin echo experiments in 3 He- 4 He mixtures, which confirmed the prediction of polarization-induced spin wave damping at zero temperature in Fermi liquids. Our experiment shows that the existence of polarization-induced spin wave damping remains an open question.
