Low temperature magnetic, transport and thermal measurements on the Ce(Pd1-x Agx ) system, with x ranging from 0 to 0.17, are presented. The magnetic structure of the ordered phase transforms from ferromagnetic to antiferromagnetic with only 2at.% Pd substitution, whereas reentrance of ferromagnetism is observed at 15at.% Ag content. We propose the break in the periodicity of the Coulomb potential (Pd is a hole-like atom, whereas Ag is an electron-like one) as the dominant effect for such a change in the magnetic behavior of this system.
