摘要

摘要:为了在相对室温条件下制备高温超导导线的接头，我们开发了元素技术。发现在YBCO/NbTi叠层薄膜中很难实现超导连接。然而，我们通过在YBCO和NbTi薄膜之间插入Ag层成功地降低了连接电阻，并确认电阻小于PPMS测量极限10 -4

Preparation of Epitaxial NbTi Thin Films at Room Temperature and Elemental Technologies for Superconducting Joint

Synopsis : In order to prepare the jointing of high-temperature superconducting wires at relative room temperature, we developed elemental technologies. It was found that the superconducting jointing was difficult to realize in stacked YBCO/NbTi thin films. However, we succeeded in reducing the jointing resistance by inserting an Ag layer between the YBCO and NbTi thin films, and confirmed that the resistance was less than the PPMS measurement limit of 10 -4 
