Abstract

YBCO thin films with BaTiO ₃ nanocolumns were fabricated on (0 0 l) oriented LaAlO ₃ substrates by metal-organic deposition (MOD). High critical current density (J _c ) up to 10 MA/cm ² has been observed on these self-assembled BaTiO ₃ nanocolumns doped YBCO films at 77 K and self-field. These BaTiO ₃ nanocolumns had no preferential orientation and were distributed randomly in the YBCO matrix. And an improved critical current density over a wide range of magnetic field in the BaTiO ₃ -YBCO composite films were found, which implies that this unique self-assembled microstructure provided strong vortex pinning in YBCO films.
