Sažetak
We report electrical resistivity and thermopower measurements of two alloy of the(UxY1-x)Ru2Si2 alloy system (x = 0.08 and 0.30). For x = 0.08, we have found evidences for impurity Kondo scattering from the lowest lying CEF levels with T-K = 10 K. The sample with x = 0.3 shows an antiferromagnetic transition at 15.3 K. Thereby we conclude that the two energy scales, T-K and T-RRKY are close to and compete against each other in dilute U of YRu2Si2.
