Abstract
YBa2Cu3O7 (YBCO) films were grown on polycrystalline silver substrates by metalorganic chemical vapor deposition (MOCVD) in high magnetic fields. It is demonstrated that a magnetic field affected the microstructure of the films on polycrystalline silver substrates. Large square-shaped grains were observed in the 0 T films. The grain size was drastically reduced by application of a few tesla fields, then changed to small grains with an irregular shape above 4 T. Furthermore, it is found that application of a large magnetic field during the deposition improved the crystallinity and grain connectivity of YBCO films, leading to the improvement of the critical current density Jc.
