The authors discuss the effect of zero-temperature attenuation, which has been recently observed in spin dynamics of spin-polarized Fermi liquid, on other Fermi-liquid processes. The transfer of this attenuation mechanism from transverse spin dynamics to longitudinal processes can be caused by the magnetic dipole interaction, namely, by the direct dipole processes and the dipole coupling between the transverse spin dynamics and the longitudinal transport and relaxation processes. They calculated the zero-temperature sound attenuation in spin-polarized Fermi liquids, corrections to the threshold of spin-wave (Castaing) instability, and the effective zero-temperature viscosity and longitudinal relaxation time in low- and high-frequency regimes.
