Abstract

Epitaxial (Tl,Bi)Sr₂Cr_0.15Ca_0.85Cu₂O_y [(Ti,Bi)-1212] films have been successfully grown on both LaAlO₃ and CeO₂/YSZ substrates by post-deposition annealing in flowing argon gas. These superconducting Tl-based, 1212-structured films on LaAlO₃ substrates have T_c values in the range of 94-100 K, and J_c values over 1.0×10⁶ A/cm² at 77 K. The films are predominately 1212 phase, with excellent epitaxy as determined by XRD θ-2θ, ω and φ scans. The films on CeO₂/YSZ substrates have T_c values in the range of 94-96 K, J_c (77 K) values close to 6×10⁵ A/cm² and excellent epitaxy on the CeO₂ buffer layers.
