摘要：

High critical current density YBa2Cu3O7-x thin films on (100)SrTiO3 were successfully prepared by laser ablation. The zero resistance transition temperature (T(c)(R = 0)) was 90.5 K and the critical current density (J(c)) at 77.3 K was 8.0 x 10(6) A/cm2 under a zero magnetic field. J(c) degraded to 1.7 x 10(4) A/cm2 in a magnetic field of 8 T parallel to the c-axis of the film, and to 4.0 x 10(5) A/cm2 in a magnetic field of 8 T perpendicular to the c-axis of the film. The characteristics of the film, mis-oriented crystallites and stacking faults, were revealed by transmission electron microscopy (TEM).
