Abstract

C-axis-oriented YBa2Cu3O7-δ films were prepared by laser chemical vapor deposition (laser CVD) using Y(DPM) 3, Ba(DPM)2/Ba(TMOD)2 and Cu(DPM)2 as precursors with enhancement by a continuous wave Nd:YAG laser. YBa 2Cu3O7-δ film almost in a single phase and that with different second phases of BaCuO2, CuBaO2, BaY2O4, CuYO2, Y2O3 and CuO were obtained by varying evaporation temperature of precursors. Ternary phase diagram as a function of evaporation amount of three precursors were obtained. The deposition rate of the C-axis-oriented YBCO film was 60 μmh-1, about 60-600 times higher than those of conventional CVD.
