Abstract
Several recent treatments of the temperature dependence of the spin susceptibility chi (T) of nearly ferromagnetic Fermi systems suggest that there is a T2lnT term in chi (T). It is shown, in a simple microscopic model, that such a term arises from retaining only one class of contributions to xi (T), and is exactly cancelled by another class, present in a spin-conserving calculation.Keywords
