Abstract

Nanocomposite (YBa₂ Cu₃ O_7-x) 0.5: (BaZrO₃) 0.5 thin films were fabricated on (001) oriented SrTiO ₃ substrates by pulsed laser deposition using a single uniformly mixed target. Both x-ray diffraction and transmission electron microscopy revealed remarkable, spontaneous formation of YBa₂ Cu₃ O_7-x (YBCO) and BaZrO₃ (BZO) multilayers. The high integrity and continuity of the multilayer made it possible to achieve a critical temperature of 88 K, given that the BaZrO₃ fraction in the films is 50 mol %. The unique self-assembled microstructure led to a surprising field dependent critical current density along the ab plane.
