Abstract
Magnetic, resistivity and specific heat measurements were performed on the CePd1-x Ni x system, which ranges between a ferromagnetic (CePd) and non-magnetic (CeNi) singlet ground state. The Curie temperature (T c ) grows with Ni concentration, reaching a maximum value ofT c =(10.5±0.1) K for 0.5≤x≤0.8. Both, the concentration dependence ofT c and the Curie-Weiss temperature (θ P ) follow the predicted competition between the magnetic exchange interactions and the Kondo effect. In the crossover region (x≅0.9) the entropy gain shows that only the doublet crystal field ground state is involved in the singlet ground state formation.
