摘要：
EXAFS, X-ray Rietveld refinement and infra-red absorption measurements have been made on Yb1-xCax (Ba0.8Sr0.2)(2) Cu3O6+delta in order to understand the effect of Ca doping on the local structure of planar Cu ion. The study indicates that, restoration of superconductivity is due to oxidation of copper ions in the CuO2 planes.
