Abstract
AbstractSingle crystals of the phase Yb3Co4–xRuxSn13 (x = 0, 0.38) were grown by the flux growth method and were characterized by single crystal and powder X‐ray diffraction. Magnetic, resistivity, and thermopower measurements were performed on both doped and undoped single crystals of Yb3Co4–xRuxSn13. The Ru‐doped compound shows a sign change of the thermopower at approximately 150 K, indicating both electron and hole conductivity, as well as a complete suppression of the ytterbium magnetic moment exhibited by undopedYb3Co4Sn13. Single crystal X‐ray diffraction studies at 100 K, 298 K, and 375 K were performed, and the results are compared to published theoretical models.
