Microstructure and current transport properties of single-layer YBa2Cu3O7−x and multiple-layer YBa2Cu3O7−x/(Ba0.05, Sr0.95)TiO3 superconductor films
Abstract
YBa2Cu3O7−x (YBCO) films grown by pulsed laser deposition on (100) LaAlO3 substrates show a strong thickness dependence on the electrical properties. Films in excess of 0.3 μm show a critical current density that decreases with increasing thickness. In contrast, nano-composite films, consisting of a stack of alternative YBCO and (Ba0.05, Sr0.95)TiO3 (BSTO) layers with a total thickness of up to 5 μm, show improved electrical properties. In …
