Query: Crystal Structure of Superconducting 1/1 Cubic Au-Ge-Yb Approximant with
  Tsai-Type Cluster   We report the synthesis of a single-phase sample of the superconducting
crystalline approximant Au64.0Ge22.0Yb14.0 and present a structure model
refined by Rietveld analysis for X-ray diffraction data.
