本文应用磁控溅射技术(MS)和混合物理化学气相沉积法(HPCVD)在单晶Al2 O3基底上制备MgB2/Ta多层膜.通过扫描电子显微镜(SEM)、原子力显微镜(AFM)、X射线衍射(XRD)和标准四线法对MgB2/Ta试样的表面形貌、晶体结构、超导特性及断面结构进行了测量研究.结果表明MgB2/Ta多层膜结构清晰,超导薄膜显示出良好的超导特性.

The MgB2/Ta multilayer were fabricated,which the MgB2 layers were grown by using the hybrid physics-chemistry vapor deposited (HPCVD)',the Ta films were prepared with Magnetron sputtering technology.Scanning electron microscopy,X-ray diffraction,atomic force microscope and our-point probe method were carried out to study cross-sectional structure,superconducting properties and crystal structure of MgB2/Ta multilayer.The results addressed that the structure of MgB2/Ta multilayer film is clear and the superconducting thin films show good characteristics.
