Y1Ba2Cu3O7-δ films with various morphologies were prepared by a chemical vapor deposition. Electron probe micro-analysis (EPMA) exhibited many precipitates with the higher copper content in the matrix of CVD films. For the best film, Tc = 92 K, Bc2(77K) = 62 T and Jc(77K, 27T) = 3.1×104 A/cm2 were obtained by resistive measurements.
