Effect of planar weight disparity on the conductivity fluctuations and critical parameters in the re₀.₅ y₀.₅ ba₂ cu₃ o₇-δ (re=sm, gd, dy, ho, eu, yb)

Synthesis and conductivity characterization of the RE₀.₅ Y₀.₅ Ba₂ Cu₃ O₇-δ (RE=Sm, Gd, Dy, Ho, Eu, Yb) superconducting materials are reported. Samples were produced by the standard solid state reaction method. Rietveldlike refinement of xray diffraction data permit to establish the crystalline appro...
