The investigation of the Ce-Ni-Ge system have permitted to establish strong correlations between physical properties of these germanides (governed by the Ce-ground state, result of a competition between Kondo and RKKY magnetic interactions) and their chemical composition. In the same phase diagram, we have taken in evidence that : (i) germanides richer in Ni are intermediate valence systems (CeNiGe, Ce3Ni4Ge4 et CeNi4.25Ge0.75) or "Heavy Fermion" systems (CeNi2Ge2 et CeNi9Ge4). Moreover, in the sequence CeNi2Ge2 → Ce3Ni4Ge4 → CeNiGe, the intermediate valence character is more and more present; (ii) germanides richer in Ge (more than 50% Ge-atomic percentage) order antiferromagnetically with Néel temperature TN decreasing with Ge-content in ...
