Abstract

Specimens of La2-xBa1+xCu2O6+delta have been synthesised with 0.25 greater than or equal to x greater than or equal to 0. The structure of La1.8Ba1.2Cu2O6.1 was determined by X-ray ponder diffractometry and high resolution electron microscopy to be isostructural to La2SrCu2O6, having an orthorhombic basic unit cell with a = 3.87, b = 3.90 and c = 20.81 Angstrom. The oxygen contents were determined by temperature programmed reduction. An 1 x 3 x 1 superstructure was observed It is believed that the non-superconducting properties of this material is resulted from the location of oxygen vacancies in the CuO2 planes.
