چکیده انگلیسی
The formation of epitaxial (La, Sr)TiO3 on biaxially-textured Ni–W metal alloy tape was examined as a conductive buffer layer for YBa2Cu3O7 film growth. A TiN epitaxial nucleation layer served as an effective template layer for subsequent (La, Sr)TiO3 film growth on the Ni–W tape. The TiN/(La, Sr)TiO3 multilayer was epitaxial on the Ni–W substrate as confirmed via four-circle X-ray diffraction. A high temperature superconducting YBa2Cu3O7 film was deposited epitaxially on the (La, Sr)TiO3/TiN/Ni–W tape. The YBa2Cu3O7 film exhibited a superconducting transition temperature of 86 K and critical current density of 0.42 × 106 A/cm2 at 77 K.
