Abstract

Rapid progress has been made on thin films of high-T_c superconducting perovskites. Here we focus on the results from one of the most studied oxide systems, 125 K TlBaCaCuO. We have produced single-phase high-T_c superconducting Tl₂Ba₂Ca₂Cu₃O₁₀ films 0.2-1.0 microm thick on MgO(100) and SrTiO₃(100) substrates by sputtering using a single oxide target. The Tl₂Ba₂Ca₂Cu₃O₁₀ films have a T_c onset at 125K and a T_c(R=0) at 116 K. Transport critical current densities of these films on SrTiO₃ substrates are as high as 10⁵ A cm^-2 at 100 K. These thallium-based films are not only strongly textured with the c-axis perpendicular to the film plane, but also epitaxial to SrTiO₃(100) substrates.
