Abstract
The evolution from an antiferromagnetic Kondo lattice, with two magnetic or dering transitions (CeCoGe3) to a non-magnetic. moderate heavy fermion comp ound (CeFeGe3) in the Ce(Co1-xFex)Ge-3 series was studied by magnetic and t ransport measurements. A tentative magnetic x-T phase diagram for the serie s was constructed. The experimental results suggest the existence of a quan tum critical point close to x(C) = 0.6. (C) 2001 Elsevier Science B.V.
