Abstract

Critical current density above 10⁴ A/cm² at 77 K and zero magnetic field have been achieved for both YBa₂Cu₃O_6.8 (YBCO) thin films on metallic substrates. A transition buffer, consisting of sub-buffers deposited at different temperatures, was used to enhance the crystallinity and the transport properties of YBCO films on metallic substrates. YBCO films were fabricated, using in-situ laser deposition, and they were strongly c-axis oriented. Critical temperature of 87 K and critical current density of 3 × 10⁴ A/cm² at 77 K were obtained for a 0.5μm-thick YBCO film. This J_c value is the highest reported for YBCO films on metallic substrates. Also, the magnetic field dependence of J_c and the mechanical properties could be improved by using Pt-coated metallic substrates.
