Title: Critical current density enhancement in YBa sub 2 Cu sub 3 O sub 6. 8 films on buffered metallic substrates

Abstract

A transition buffer, consisting of subbuffers grown at different temperatures, was used to enhance the crystallinity and the transport properties of YBa{sub 2}Cu{sub 3}O{sub 6.8} (YBCO) films on metallic substrates. Films were fabricated using {ital in} {ital situ} laser deposition and were strongly {ital c}-axis oriented. Critical temperature of 87 K and critical current density of 3{times}10{sup 4} A/cm{sup 2} at 77 K were obtained for a 0.5-{mu}m-thick YBCO film with a 0.2 {mu}m transition yttrium- stabilized ZrO{sub 2} buffer layer. Also, the magnetic field dependence of {ital J}{sub {ital c}} could be enhanced by using Pt-coated metallic substrates.
