Effects of Impurities on Spin Fluctuations in Almost Ferromagnetic Metals

We investigate the effects of the mean free path on the spin susceptibility of almost ferromagnetic metals. Using these results, we calculate the low-temperature specific-heat contribution of the spin fluctuations. While the term linear in temperature T is unaffected by the mean free path, we find that the T³ ln T contribution is rapidly modified by impurities, in contrast to the phonon case.
