Abstract

Thermopower and superconductivity measurements are reported on CeRu 3Si 2 and Ce 1-xLa xRu 3Si 2. For the compound, a mixed valence derived contribution to the thermopower is found. The transition temperatures T c(x) of the alloys interpolate smoothly between T c(CeRu 3Si 2)=1.0K and T c(LaRu 3Si 2)=7.2K.
