Influence of structural changes induced by co-doping in YBCO on superconductivity
Description
The single-phase samples of Y1-xCaxBa2-xLaxCu3Oy (YCBLCO) were synthesized with x<0.2 and characterized by DC magnetization measurement and x-ray diffraction (XRD). The structure of the samples was refined by the Rietveld method. Although the carrier concentration in the samples is constant for different dopant levels, the superconductivity evidently changes. We attribute the decrease in Tc to charge redistribution in the crystalline lattice. Comparing the change of the Tc value caused by structural influences and carrier concentration, it is suggested that the influence of structural changes on the superconductivity is independent of that induced by carrier concentration
