Sažetak
We report on the resistivity and thermopower measurements together with the microstructural investigations of two highly concentrated alloys of the U<sub>x</sub>Y<sub>1-x</sub>Ru<sub>2</sub>Si<sub>2</sub> alloy system, for x = 0.5 and x = 0.67, nominally. Microstructural analysis shows the existence of two different crystalline phases at the room temperature: the solid solution U<sub>c</sub>Y<sub>1-c</sub>Ru<sub>2</sub>Si<sub>2</sub> (c < x) phase and the phase which can be represented by chemical formula URu<sub>2</sub>Si. We show that the uranium single ions dissolved in the YRu<sub>2</sub>Si<sub>2</sub> matrix exhibit the ordinary or single-channel Kondo effect described by the Coqblin–Schrieffer Hamiltonian. In the light of the obtained results, the URu<sub>2</sub>Si<sub>2</sub> compound is discussed.
