Abstract

Superconducting thin films consisting perdominantly of yttrium barium copper oxide have been prepared by oxygen annealing of metal films formed by using electron-beam evaporation to deposit a three-layer sequence of Cu, Ba, and Y in nominally stoichiometric proportions, then repeating the sequence five times. For the best superconducting films, which were prepared on yttria-stabilized cubic zirconia substrates, the onset of superconductivity occurred at 94 K and zero resistivity was observed at 72 K. For the best films prepared on sapphire substrates, the corresponding temperatures were 95 and 40 K.

Preparation of superconducting YBa2Cu3O/sub x/ thin films by oxygen annealing of multilayer metal films

Journal Article Tsaur, B; DiIorio, M; Strauss, A - Appl. Phys. Lett.; (United States)

Superconducting thin films consisting predominantly of YBa2Cu3O/sub x/ have been prepared by oxygen annealing of metal films formed by using electron beam evaporation to deposit a three-layer sequence of Cu, Ba, and Y in nominally stoichiometric proportions, then repeating the sequence five times. For the best superconducting films, which were prepared on yttria-stabilized cubic zirconia substrates, the onset of superconductivity occurred at 94 K and zero resistivity was observed at 72 K.

Effect of stoichiometry and post-annealing conditions on magnetron sputtered films of YBa/sub 2/Cu/sub 3/O/sub 7/ on cubic zirconia

Journal Article Wiesmann, H; Chen, D; Sabatini, R; ... - J. Appl. Phys.; (United States)

High-quality YBa/sub 2/Cu/sub 3/O/sub 7/ films supported on yttrium stabilized cubic zirconia were made by simultaneous reactive magnetron sputtering using yttrium, barium, and copper metal targets. Superconductivity onsets of 92 K with transition widths of 1.5 K (10%--90%) have been achieved on yttrium stabilized cubic zirconia substrates. Various aspects of the deposition processes are described and the effect of deposition parameters and post-annealing on thin-film stoichiometry, structure, and superconducting properties is discussed.

Preparation and properties of YBa[sub 2]Cu[sub 3]O[sub 7] thin films on sapphire with Yttria-stabilized zirconia buffer layer

Journal Article Tian, Y; Xu, S; Lu, H; ... - Journal of Superconductivity; (United States)

YBa[sub 2]Cu[sub 3]O[sub 7] superconducting thin films were deposited on R-plane sapphire substrates with Yttria-stabilized zirconia buffer layer by laser ablation. The structure of the films was characterized by X-ray diffraction. Superconducting transitional temperatures as high as [ge]90 K and critical current densities up to 2.2 [times] 10[sup 6] A/cm[sup 2] (77 K) were achieved. The results of Auger depth profile showed that no obvious diffusion occurred between the substrate and the YBa[sub 2]Cu[sub 3]O[sub 7] thin film.

Structure and superconducting properties of YBa sub 2 Cu sub 3 O sub 7 minus x films prepared by nitrogen laser evaporation and CO sub 2 laser annealing in oxygen

Journal Article Serbezov, V; Benacka, S; Hadgiev, D; ... - Journal of Applied Physics; (USA)

Superconducting YBa{sub 2}Cu{sub 3}O{sub 7{minus}{ital x}} thin films were obtained under high vacuum (10{sup {minus}5} Torr) on substrates of polycrystalline Al{sub 2}O{sub 3} sapphire, SrTiO{sub 3}, and Si, having zero resistance at 81, 85, 87, and 79 K, respectively. A N{sub 2} laser of 3.5 J cm{sup {minus}2} energy density was used for the evaporation. The substrates were heated by a cw single-mode CO{sub 2} laser and the annealing was performed by the same laser in O{sub 2} atmosphere. Local planar superconducting regions were obtained by focusing the radiation of the cw CO{sub 2} laser upon the films. The filmsmore »« less

Sequential Ar-O sub 2 sputtering of Y sub 2 O sub 3 , BaF sub 2 , and CuO targets for preparation of Y-Ba-Cu-O superconducting films without wet-O sub 2 annealing

Journal Article Bhushan, M; Strauss, A; Finn, M - Applied Physics Letters; (USA)

Superconducting Y-Ba-Cu-O (YBCO) films have been prepared by {ital ex situ} O{sub 2} annealing of multilayer films deposited on yttria-stabilized zirconia substrates by sequential rf diode sputtering of Y{sub 2}O{sub 3}, BaF{sub 2}, and CuO targets, all of which are chemically stable. If sputtering is performed in an Ar ambient, the as-deposited films contain sufficient F to require its removal by annealing in wet O{sub 2} at about 800 {degree}C or above before the superconducting YBCO phase can be formed by annealing in dry O{sub 2}. However, sputtering in an Ar-O{sub 2} ambient greatly reduces the F content, making itmore »« less
