Abstract
High-quality YBa2Cu3O7 (YBCO) films were grown on polycrystalline silver su bstrates by a metalorganic chemical vapor deposition process in high magnet ic fields. Property characterizations revealed that the YBCO films deposite d in high magnetic fields have excellent structural and superconducting pro perties. At 77 K, the transport critical current densities of such films we re over 10 000 A/cm(2) in the field of 1 T (H parallel toc axis). The impro vement of the critical currents in YBCO films deposited in high magnetic fi elds is correlated with the better intergrain connections, as observed by s canning electron microscopy.
