Resumen en inglés

The investigation on Ce--Ni--Ge phase diagram indicates a relationship between the physical behavior of these ternary germanides and their chemical composition. Those with more than 50 % Ge-atomic percentage order antiferromagnetically, with Néel temperatures TN decreasing with Ge-content. The Ce-magnetic moment at 1.4 K, determined by neutron powder diffraction, also decreases with Ge-content. As for the ternary germanides rich in Ni (\geq 33%), they can be classified as intermediate valence compounds (CeNiGe, Ce3Ni4Ge4 and CeNi4.25Ge0.75) or heavy-fermions systems (CeNi2Ge2 and CeNi9Ge4).< Leer menos
