Abstract Thin films of YBa/sub 2/Cu/sub 3/O/sub 7-//sub y/ were prepared by magnetron sputtering. The films were characterized by x-ray diffraction, in situ x-ray photoelectron spectroscopy to determine the as-deposited oxygen content for various substrate temperatures, and scanning electron microscopy to analyze the microstructure. The orthorhombic phase was observed after an ex situ 700 /sup 0/C anneal. We have obtained films which were completely superconducting at 82 K with 6 K transition widths.
