High quality YBa2.Cu3O6 +x(YBCO) superconductive thin films have been fabricated on the SrTiO3(100) substrate using laser molecular beam epitaxy (laser-MBE). The active oxygen source was used, which made the necessary
ambient oxygen pressure be 2–3 orders lower than that in pulsed laser deposition (PLD). Tc0 is 85–87 K, and Jc, 1.0 × 106 A/cm2. Atomic force microscopy (AFM) measurements show that no obvious particulates can be observed and the root mean square roughness
is 7.8 nm. High stability DC superconducting quantum interference devices (DC-SQUID) was fabricated using this YBCO thin film. 相似文献

LB膜法制备Y2O3掺杂的CeO2超薄陶瓷膜的X光电子能谱(XPS)研究 总被引:1,自引:0,他引:1
利用LB膜技术发展了一种制备组分可控的超薄陶瓷膜的方法。以Ce,Y的β-二酮络合物作为表面离子,替代传统的亚相离子,制得混合LB膜。并将它作为前驱物成功制得了Y2O3掺杂的CeO2(YDC)超薄膜。XPS谱表明,膜中Ce与Y的含量比控制得很好。 相似文献
