Abstract

We explain the anomalous temperature dependence of spin diffusion in liquid ↑3 and 3-4He mixtures. The anomaly is an experimental manifestation of a unique zero-temperature attenuation in the Fermi liquid theory. We extended our microscopic theory of spin dynamics in spin-polarized Fermi liquids to finite temperatures. The zero-temperature attenuation changes the behavior of the spectrum near the singular point. The data indicate that the superfluid transition temperature for 3He in 3-4He mixtures is much lower than the current estimates.
