Resistivity effects in the Ce(Pd,Rh)3B1 and Ce(Rh,Ru)3B2 system

We report Ce-L3-valence state and temperature-dependent resistivity results on two pseudoternary alloy series: CeT3Bn where n=1 with T=(Pd, Rh) and where n=2 with T=(Rh,Ru). Our results indicate that both series pass continuously from a Kondo local-moment regime to a mixed valent regime to a saturat...

Description
Summary:We report Ce-L3-valence state and temperature-dependent resistivity results on two pseudoternary alloy series: CeT3Bn where n=1 with T=(Pd, Rh) and where n=2 with T=(Rh,Ru). Our results indicate that both series pass continuously from a Kondo local-moment regime to a mixed valent regime to a saturated valence regime with decreasing 4d electron concentration on the T sublattice. We correlate the temperature-dependent resistivity results with the Ce-L3-valence variation for both series. For the n=1 series, Kondo-type behavior appears in the local-moment regime, while for the n=2 series, ferromagnetism appears in the local-moment regime. We also note that in the mixed valence regime, for both series, the absolute value of the resistance drops rapidly, indicating a loss of magnetic scattering.
