Abstract
Superconducting B4Sr2Can-1CunOx (BSCCO) (n = 2-5) thin films were prepared by sputtering. phase intergrowth among n = 2-3, 3-4 and 4-5 phases was obse rved. The molar fraction of each phase in the mixed crystal of the deposite d films was determined by X-ray diffraction analyses and investigated as a function of O-2 gas pressure during sputtering. We investigated the changes of the superconducting properties by molar fraction of each phase. The fab rication conditions for selective growth of the single It = 2, 3 and 4 phas es in BSCCO thin film are discussed. (C) 2000 Elsevier Science B.V. All rig hts reserved.
