    Abstract
    A significant effort has been made recently to develop second-generation HTSC tapes. In these tapes, ReBaCuO (rare-earth barium copper oxide - YBCO) thin films are produced on metallic substrates, such as textured Ni, NiW alloys and stainless steel. To prevent the interdiffusion of elements between metal substrate and superconducting material, and to match the YBCO lattice parameters with the substrate texture, different buffer layers were deposited on the substrate. In commercially available HTSC tapes, several buffer layers are typically used to obtain high-quality YBCO superconductor coatings (i.e. appropriate texture, ...

    A significant effort has been made recently to develop second-generation HTSC tapes. In these tapes, ReBaCuO (rare-earth barium copper oxide - YBCO) thin films are produced on metallic substrates, such as textured Ni, NiW alloys and stainless steel. To prevent the interdiffusion of elements between metal substrate and superconducting material, and to match the YBCO lattice parameters with the substrate texture, different buffer layers were deposited on the substrate. In commercially available HTSC tapes, several buffer layers are typically used to obtain high-quality YBCO superconductor coatings (i.e. appropriate texture, defect-free and with a high critical current density, Jc,). Many existing HTS tape technologies use a variety of buffer layer architecture, which include YSZ, MgO, Y2O3 and CeO2 nm-thick layers and their combinations.
