【摘要】 采用中空柱状阴极直流磁控溅射方法制备了大面积ＹＢＣＯ 超导薄膜．应用ＸＲＤ 方法，对在３０ ×３０ｍｍ２ＬａＡｌＯ３ 衬底上沉积的ＹＢＣＯ 薄膜进行了结晶完整性、均匀性的测定．对同一样品，使用透射电子显微镜对薄膜和衬底间的界面进行了研究．更多还原

【Abstract】 Large area YBCO superconducting films are prepared by using hollow cylindrical cathode, dc magnetically controlled sputtering assembly. XRD is used to investigate the perfection and the homogeneity of the crystallized YBCO film which is of 30×30mm\+2 upon LaAlO\-3 substrate. For the same specimen, TEM is used to study the film /substrate interface.更多还原
