摘要：

High-temperature superconductor GdBa2Cu3O7 thin films were epitaxially grown in situ on (100) oriented ytrrium-stabilized zirconia single-crystal substrates by dc magnetron sputtering using a single planar target. All samples prepared in continual 12 runs have zero-resistance transition temperature Tc0 more than 90 K and a transition width 1-2 K. The best films have a Tc0 of 92.5 K, a transition width of 0.7 K, and a critical current density of 1.4×106 A/cm2 at 77 K. The reproducibility is very good. X-ray diffraction spectra analysis in different geometries showed epitaxial growth with the c axis normal to the film surface.
