We describe the effect of zero-temperature attenuation, which has been recently observed in spin dynamics of Fermi liquids, on various processes in helium and ferromagnetic systems. After a brief review of theoretical and experimental data on zero-temperature attenuation in transverse spin dynamics of helium systems, we discuss coupling between longitudinal and transverse processes, the Castaing instability in 3He and 3He-4He mixtures, and applications to pure ferromagnetic metals.
