摘要：

We have developed a simple alternative buffer layer architecture for the rolling-assisted biaxially textured substrates (RABiTS) approach. Buffer layers with both oxygen and metal diffusion barrier properties are of interest. Cube textured magnesium oxide MgO buffers were grown directly on biaxially textured Ni and Ni-W3 at.% substrates using electron beam evaporation. We have also grown epitaxial MgO layers on 2 m long textured Ni-W3 at.% tapes in a reel-to-reel e-beam evaporation. Highly textured LaMnO3 (LMO) buffers were grown on MgO-buffered Ni substrates using rf sputtering. MgO and LMO buffers have been proved to be good oxygen diffusion barriers and Ni diffusion barriers, respectively. YBCO films with a J(C) of 1 x 10(6) A cm(-2) at 77 K and self-field were grown on this newly developed architecture of LMO/MgO/Ni using pulsed laser deposition.
