[en] We have measured the electronic resistivity and thermopower of liquid Cu_1-cCe_c, Cu_1-cLa_c, and Ag_1-cCe_c alloys for c < 0.4. In all of the alloys the resistivity is very similar, rising smoothly and steeply as c increases, but at all times remaining less than 200 μΩ cm. The thermopower is also featureless and metallic. However, the temperature coefficient, α=(1/ρ)dρ/d t, displays in the Cu alloys a minimum for Cu₆ R E (R E = rare earth), which furthermore is negative for Cu₆Ce; a negative temperature coefficient is also seen for Ag₃Ce. We also present the results of an investigation of neutron diffraction scattering from liquid Cu₆Ce, and the results of a reverse Monte Carlo (RMC) analysis of the structure data, which shows evidence of ordering in the liquid, with characteristics similar to those of crystalline Cu₆Ce. We discuss several possible explanations for the negative temperature coefficient of both Ag and Cu alloys, and conclude that its origin lies in the presence of chemical short-range order. (author).
