Abstract
We have investigated the role of spin-independent and spin-dependent impurity scattering in itinerant Fermi systems which have a large susceptibility enhancement and find that at very low temperatures the smearing of the Fermi surface due to spin-independent scattering leads to a stronger temperature dependence of the specific heat than for pure systems, but that at still lower temperatures spin-dependent scattering changes the temperature dependence to the usual power-series expansion.Keywords
