Abstract

A transition buffer, consisting of subbuffers grown at different temperatures, was used to enhance the crystallinity and the transport properties of YBa₂Cu₃O_6.8 (YBCO) films on metallic substrates. Films were fabricated using in situ laser deposition and 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 0.5-μm-thick YBCO film with a 0.2 μm transition yttrium- stabilized ZrO₂ buffer layer. Also, the magnetic field dependence of J _c could be enhanced by using Pt-coated metallic substrates.
