"Intermediate valence in single crystals of (Lu1−x Y b x )3Rh4Ge13 (0 ≤ x ≤ 1)." <i>APL Materials,</i> 3, (2015) AIP Publishing LLC: 41511. http://dx.doi.org/10.1063/1.4913742.https://hdl.handle.net/1911/80200Single crystals of (Lu1−x Y b x )3Rh4 Ge 13 were characterized by magnetization, specific heat, and electrical resistivity measurements. Doping Yb into the non-magnetic Lu3Rh4 Ge 13 compound tunes this cubic system’s properties from a superconductor with disordered metal normal state (x < 0.05) to a Kondo for 0.05 ≤ x ≤0.2 and intermediate valence at the highest Yb concentrations. The evidence for intermediate Yb valence comes from a broad maximum in the magnetic susceptibility and X-ray photoelectron spectroscopy. Furthermore, the resistivity displays a local maximum at finite temperatures at intermediate compositions x, followed by apparent metallic behavior closest to the Yb end compound in the series.engAll article content, except where otherwise noted, is licensed under a Creative Commons Attribution 3.0 Unported License.Journal articleGermaniumelectrical resistivityx-ray photoelectron spectroscopyKondo effectsuperconductivityhttp://dx.doi.org/10.1063/1.4913742
