Publication Date



Single crystals of the phase Yb3Co4-xRu xSn13 (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-xRuxSn 13. 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. Copyright © 2011 WILEY-VCH Verlag GmbH & Co.
