Popis: Substitution of La and Ca on the Y and Ba sites in the 1-2-3 structure permits the investigation of charge transfer in the solid solution La1+xCayBa2−x−yCu3O7+δ for doping over a wide compositional range. The superconducting, structural and optical properties of this system are reported. Single-phase samples have been found for 0
