The absence of a linear behaviour of the dependence of the resistance R(T ) over a temperature interval 77-300 K was observed for ceramic superconductors YBa 2 Cu 3 O 7-δ and thick polycrystalline films of the same composition with the addition of silver. A comparative analysis of the excess conduct
Equal amount Pr and Ca double-doping Y 1À2x Pr x Ca x Ba 2 Cu 3 O 7Àd with 0 6 x 6 0.14 have been investigated by X-ray diffraction, resistivity, and X-ray photoemission spectroscopy (XPS). The deviation of the linearly decreasing of T c vs. x curve was observed when x < 0.10. The resistivity and th
