| Abstract: | The crystal structure of the superconducting phase of the Y-B-C-O system has been determined by the single crystal X-ray diffraction technique. The crystal is orthorhombic with space group Pmmm, lattice parameters a=3.858 A(2), b=3.857A.(2), c=11.653A(3). The stoichiometric formula determined in the experiment is YBa_2 Cu_(2.84)O_(6.58) |
