Non-Fermi liquid behavior and Griffiths phase in {\it f}-electron compounds

Strongly Correlated Electrons 2009-10-30 v2

Abstract

We study the interplay among disorder, RKKY and Kondo interactions in {\it f}-electron alloys. We argue that the non-Fermi liquid behavior observed in these systems is due to the existence of a Griffiths phase close to a quantum critical point. The existence of this phase provides a unified picture of a large class of materials. We also propose new experiments that can test these ideas.
