An improved fabrication of superconducting films is disclosed whereby a multi-phase Y-Ba-Cu-O compound is utilized. The film is formed by sputtering of a target material consisting of the superconducting 123 phase Y1Ba2Cu3O7 onto the green 211 phase Y2BaCuO5. After annealing, the superconducting characteristic, of the formed film, in terms of transition width and Tc, are improved over those using other oxide compounds as substrates. |
