Resolution of the discrepancy between the variation of the physical   properties of Ce1-xYbxCoIn5 single crystals and thin films with Yb   composition
  Measurements of physical properties show that Yb enters the single crystals systematically and in registry with the nominal Yb concentration x of the starting material dissolved in the molten indium flux.
