摘要：

High T//cEr-Ba-Cu-O superconducting films were prepared by rf sputtering. The films revealed superconducting transition temperatures for onset and zero resistance of 95 K and 84 K, respectively. Although the X-ray diffraction measurement showed the film consists of an orthorhombic structure with the lattice constants a, b and c, respectively, of 3. 883 A, 3. 830 A and 11. 70 A, most of the surface layer was found by electron spectroscopy for chemical analysis (ESCA) to be significantly Er-deficient.
