Abstract
The crystallography, electrical resistivity, magnetic susceptibility a nd magnetisation of the CexPr1-xNi5, CexNd1-xNi5 and PrxNd1-xNi5 compo unds are presented. The evolution from a magnetic order in NdNi5 to th e non magnetic state in PrNi5 (singlet ground level) and CeNi5 (interm ediate valence) is discussed. The Curie temperature of NdNi5 decreases proportionally to the amount of substituting Pr or Ce ions. CEF effec ts on the singlet ground state on the Pr based compounds are detected by resistivity and susceptibility measurements. The influence of the c ompetition between the intermediate valence and the singlet ground sta te in CexPr1-xNi5 are also analyzed. (C) 1997 Elsevier Science Ltd.
