Abstract
We propose an explanation for the recently observed non-Fermi-liquid behavior of metallic alloys : Near , the specific heat is proportional to , and the resistivity increases linearly with temperature over a wide range of . These features follow from a model in which three-dimensional conduction electrons are coupled to two-dimensional critical ferromagnetic fluctuations near the quantum critical point . This picture is motivated by the neutron scattering data in the ordered phase ( ) and is consistent with the observed phase diagram.
