摘要：

Nanocomposite (YBa2Cu3O7-x)(0) (5): (BaZrO3)(0 5) thin films were fabricated oil (00 1) oriented SrTiO3 Substrates by pulsed laser deposition using a single uniformly mixed target. Both x-ray diffraction and transmission electron microscopy revealed remarkable, spontaneous formation of YBa2Cu3O7-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. (C) 2009 American Institute of Physics. [doi: 10.1063/1.3257238]
