The Doniach's diagram has been originally proposed to describe the competition between the local Kondo effect and the inter-site RKKY interactions in cerium compounds. Here we discuss the extension of this diagram to different variations of Kondo lattice model. We consider (a) ordered cerium compounds where the competition between magnetic order and Kondo effect plays an important role, as in CeRh2Si2, (b) disordered cerium systems with competing spin glass phase, magnetic ordered phases and a Kondo phase, as in the heavy fermion cerium alloy CeCuxNi1-x and (c) uranium compounds where a coexistence between Kondo effect and ferromagnetic order has been observed, as in UTe. We show that all these cases can be described by a generalized Doniach phase diagram. (C) 2008 Elsevier B.V. All rights reserved.
