Abstract
We report a low-temperature resistivity-minimum anomaly along with the Cr-like one in Y- and Sc-doped systems, as previously seen for heavy rare-earth and Th-doped systems. In the Y alloys, it is found that this low-temperature-minimum anomaly exists even up to 50% Y. However it is easily destroyed by alloying Ir on the Ru site of already Sc-doped samples. For Sc, the Cr-like anomaly moves towards lower temperatures before disappearing at 15% Sc, while we observe that the itinerant antiferromagnetic transition becomes a spin-glass type at 50% Y. The concentration dependence of the various effects varies for Sc, Y, La, and Ce substitutions.Keywords
