Abstract
In situ laser deposition was used to fabricate YBa2Cu3O6.8 (YBCO) films on metallic substrates. With a buffer layer, YBCO films were strongly c‐axis oriented. Tc = 83 K and Jc= 4000 A/cm2 at 77 K were obtained for a 0.5 μm YBCO film with a 0.15 μm yttrium‐stabilized ZrO2 buffer layer. There was negligible interdiffusion occurring at the interfaces. The n value of YBCO films ranged from 1.4 to 1.5.Keywords
