Crystal Structure of (Pb/Cu)SrLaCuOy Superconductor
Abstract
The crystal structure of a new superconducting lead cuprate, (Pb/Cu)SrLaCuOy, has been investigated. The Rietveld refinement for powder X-ray diffraction data of a ceramic sample was performed. It revealed that the structure is composed of (Pb/Cu)-O single layers and Cu-O6 octahedrons. The properties of block layers between the apexes of two Cu-O6 octahedrons in p-type cuprate superconductors are discussed.
