Abstract

The introduction of Cu in the CeNi compound maintains the same crystallographic CrB-type structure up to CeNi0.85Cu0.15. The crystallographic structure of several compositions in the neighbourhood of this limit has been determined from single crystals in a 4-circle diffractometer. The thermal expansion coefficients of CeNi0.9Cu0.1 behave similar to those of CeNi. The Cu substitution disturbs the intermediate valence behaviour of CeNi, inducing non-zero magnetic moments at low temperatures and suggesting a cluster-glass behaviour.
