Abstract

The role of substrate-induced microstructure on transport properties in c-axis oriented epitaxial Tl{sub 2}Ba{sub 2}CaCu{sub 2}O{sub x} films grown on LaAlO{sub 3} and SrTiO{sub 3} has been studied. For a magnetic field parallel to the Cu-0 planes, resistivity and the critical current density, J{sub c}, have been measured as a function of angle {theta} between the applied field and the direction of transport current. Resistivity dips and enhancement of the critical current density, J{sub c}, were observed for magnetic fields applied parallel to the substrate twins in LaAlO{sub 3} in high fields ({ge} 2 T). Meanwhile for films on SrTiO{sub 3}, resistivity and J{sub c} were Lorentz-force independent.

Effect of substrate-twin-induced microstructure on transport properties of epitaxial Tl{sub 2}Ba{sub 2}CaCu{sub 2}O{sub x} films in a magnetic field

Preparation and properties of Tl[sub 2]Ba[sub 2]CaCu[sub 2]O[sub 8] thin films

Journal Article Johansson, L; Claeson, T; Ivanov, Z; ... - Journal of Superconductivity; (United States)

An ex situ process has been developed to produce thin superconducting Tl[sub 2]Ba[sub 2]CaCu[sub 2]O[sub 8] films. The properties of films grown on different substrates using different annealing regimes were studied. Critical temperatures of 103-107 K were measured on films prepared in a broad range of annealing temperatures on SrTiO[sub 3], LaAlO[sub 3], and Y-ZrO[sub 2] substrates. A critical current density, J[sub c], of 2 [times] 10[sup 6] A/cm[sup 2] at 77 K was measured on LaAlO[sub 3]. Film morphology was studied by SEM, AFM, and STM.

Preparation and characterization of Tl sub 2 Ba sub 2 CaCu sub 2 O sub 8 films on (100) LaAlO sub 3

Conference Holstein, W; Parisi, L; Kountz, D; ... - IEEE Transactions on Magnetics (Institute of Electrical and Electronics Engineers); (United States)

A two-step process for the fabrication of 0.12-1.20 {mu}m-thick Tl{sub 2}Ba{sub 2}CaCu{sub 2}O{sub 8} films on (100) LaAlO{sub 3} has been developed. The process involves the deposition of a BaCaCuO precursor film at low temperature by rf magnetron sputtering, followed by annealing in the presence of Tl{sub 2}O vapor to convert the precursor film into Tl{sub 2}Ba{sub 2}CaCu{sub 2}O{sub 8}. Over a distance of 4 cm, film composition was Tl:Ba:Ca:Cu = 2.05 {plus minus} 0.09:2.05 {plus minus} 0.06:1.0 {plus minus} 0.3:1.94 {plus minus} 0.6 and thickness was uniform to within 6%. The films contain only trace quantities of secondary phasesmore »« less
Preparation of Tl sub 2 Ba sub 2 CaCu sub 2 O sub 8 superconducting thin films on LaAlO sub 3 substrates from metalorganic-chemical-vapor-deposition-prepared precursor films

Journal Article Ladd, J; Collins, B; Matey, J; ... - Applied Physics Letters; (United States)

Single phase Tl{sub 2}Ba{sub 2}CaCu{sub 2}O{sub 8} thin films have been deposited on single-crystal LaAlO{sub 3} substrates, (100) orientation, via a two-step deposition process. First, Ba-Ca-Cu-O precursor films were deposited by metalorganic chemical vapor deposition (MOCVD) using barium, calcium, and copper-tetramethyl-heptanedionate, (tmhd){sub 2}, source materials under reduced pressure in an oxygen/argon atmosphere. Substrate temperatures were between 500 and 600 {degree}C. Thallium was then incorporated by heating the films in a confined surface configuration with an unfired pellet of Tl{sub 2}Ba{sub 2}CaCu{sub 2}O{sub {ital x}} composition at 870 {degree}C for 0.1 h. The resultant films (0.5--1 {mu}m thick) showed a preferredmore »« less

LaNiO{sub 3} buffer layers for high critical current density YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} and Tl{sub 2}Ba{sub 2}CaCu{sub 2}O{sub 8{minus}{delta}} films

Journal Article Carlson, C; Parilla, P; Siegal, M; ... - Applied Physics Letters

We demonstrate high critical current density superconducting films of YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} (YBCO) and Tl{sub 2}Ba{sub 2}CaCu{sub 2}O{sub 8{minus}{delta}} (Tl-2212) using LaNiO{sub 3} (LNO) buffer layers. YBCO films grown on an LNO buffer layer have only a slightly lower J{sub c} (5 K, H=0) than films grown directly on a bare LaAlO{sub 3} substrate. YBCO films grown on LNO buffer layers exhibit minor microstructural disorder and enhanced flux pinning. LNO-buffered Tl-2212 samples show large reductions in J{sub c} at all temperatures and fields compared to those grown on bare LaAlO{sub 3}, correlating to both {ital a}-axis grain and nonsuperconductingmore »« less
