Abstract
We have developed a simpler alternative buffer layer architecture for Rolling-Assisted Biaxially Textured Substrates (RABiTS) approach. Cube textured MgO buffers were grown directly on biaxially textured Ni and Ni-W substrates. MgO has been proved to be a good diffusion barrier for oxygen. In addition, LaMnO3 (LMO) has been identified as a compatible buffer layer for MgO and it also provides a good template for growing high current density YBCO films. We have optimized the growth of LMO layers on MgO/Ni using rf sputtering. Sputtered CeO2 cap layers were also grown on LMO layers for compatibility with Ex-situ YBCO process. YBCO films with a Jc of 500,000 A/cm2 at 77 K and self-field were grown on this newly developed architecture of CeO2/LMO/MgO/Ni using pulsed laser deposition.
