| 摘 要： | 采用电子束沉积制备YBCO超导薄膜,研究了760℃—840℃的不同退火温度下高温热处理对YBCO薄膜双轴织构、表面形貌及超导性能的影响。超导临界电流密度测试、X射线衍射(XRD)和扫描电镜(SEM)的结果表明,退火温度在在800℃时,YBCO薄膜具有良好的织构和平整致密的表面形貌,在77K自场下的临界电流密度J可达4.2×106/cm2。

| Abstract: | Epitaxial YBCO superconducting films were deposited by E-beam evaporation on single crystalline LaAlO3(001)substrate,and microstructure and superconductivity of YBCO thin films were analyzed by X-ray diffraction,scanning electron micrograph and Jc scan system.We found that YBCO films fired at 800℃ have the best biaxial texture and Jc attached 4.2×106/cm2(77K,0T). |
