摘要：

Structural and transport measurements for quasimultilayers of Ir-doped YBa2Cu3O7-delta prepared by pulsed-laser deposition are presented. Due to metallic Ir doping, BaIrO3 particles form during film growth. These nanosized particles, having a perovskite structure, grow epitaxially in cube-on-cube relationship inside the film. A strong increase in pinning force density and, hence, J(c) was found. (C) 2005 American Institute of Physics.
