摘要
利用直流磁控溅射技术制备了Ho替代的YBCO超导薄膜,X射线技术(θ-2θ扫描:θ-θ扫描及—扫描)、SEM和电子通道花样(ECP)测试表明,所制备的掺杂薄膜具有高平面内外延性和平面外外延性。发现掺杂薄膜的临界电流密度Jc比YBCO薄膜的有不同程度的提高,掺杂量x=04时有最大值。
The Ho substitution YBCO thin films were prepared by using single target method by DCmagnetron sputtering technique. The thin films properties such as Tc and Jc were mainly effected by the deposition temperature Ts. The Jc values in all of the substituted films increased, with an optimal effect achieved at x=04 concentration at the 77 K and 0~3 T.
