    Superconducting Behavior of YBa2Cu3O6.8/Bi2Sr2CanCun+1Ox Multilayers

    Composite YBCO/BSCCO films on MgO(lOO) substrates were fabricated by using laser deposition. The structures and transport properties of these composite films were studied. The model of 3D percolating network i...

    Critical current and microstructure of uniaxially aligned, polycrystalline YBa2Cu3O7−δ

    Three processing routes that generate uniaxial alignment but otherwise yield very different microstructure and critical current are compared. Fine grain size and c-axis alignment are obtained in magnetically a...

    Microstructures in Y-Ba-Cu-O Thin Films Investigated by XAFS Techniques

    Superconducting films of YBa2Cu3O7-6 obtained by laser ablation on MgO and ZrO2 substrates were investigated by soft x-ray absorption fine structure technique (XAFS) at O K-edge. Local environment around oxygen a...

    Superconducting Films of Bi-Sr-Ca-Cu-O by Laser Deposition

    Superconducting Bi-Sr-Ca-Cu-O (BSCCO) films have been grown on single crystal [100] MgO by laser deposition. The films are highly c-axis oriented perpendicular to the substrate. The 2212, 2223 and 2234 phases ...

    Multilayer Flexible Oxide Superconducting Tapes

    Superconducting Y-Ba-Cu-O films have been grown on mirror-finished flexible stainless steel substrates. Plasma assisted laser deposition (PLD) technique enabled us to grow these films at a reduced substrate te...
