摘要：

We report the results of experiments with ion-beam-assisted deposition (IBAD) of MgO using in-situ monitoring with Reflected High-Energy Electron Diffraction (RHEED). Strips of polished Haynes 242 and Inconel 625 nickel-based super-alloys have been used as substrates for these experiments. The inplane texture of the MgO, as measured by x-ray phi scan, resulted in FWHM values between 11 and 15 degrees. Using pulsed-laser deposition, the IBAD MgO template films were then overcoated with buffer layer films and a final superconducting film of YBa2Cu3O7-delta. The best superconducting transport properties measured on these YBCO films were: an Ic (75K, self-field, 1 cm wide) of 41.6 A, and a narrow-bridge J(c) (1.35 mu m thick film) of 0.46 Ma/cm(2).
