Abstract

High-quality YBa2Cu3O7 (YBCO) films were grown on polycrystalline silver substrates by a metalorganic chemical vapor deposition process in high magnetic fields. Property characterizations revealed that the YBCO films deposited in high magnetic fields have excellent structural and superconducting properties. At 77 K, the transport critical current densities of such films were over 10 000 A/cm2 in the field of 1 T (H∥c axis). The improvement of the critical currents in YBCO films deposited in high magnetic fields is correlated with the better intergrain connections, as observed by scanning electron microscopy.
