Method of fabricating a (1223) Tl-Ba-Ca-Cu-O superconductor

Patent Tkaczyk, John Eric [Delanson, NY]; Lay, Kenneth Wilbur [Schenectady, NY]; He, Qing [Knoxville, TN]

A method is disclosed for fabricating a polycrystalline <223> thallium-containing superconductor having high critical current at elevated temperatures and in the presence of a magnetic field. A powder precursor containing compounds other than thallium is compressed on a substrate. Thallium is incorporated in the densified powder precursor at a high temperature in the presence of a partial pressure of a thallium-containing vapor.

High temperature superconductor step-edge Josephson junctions using Ti-Ca-Ba-Cu-O

Patent Ginley, David S [Evergreen, CO]; Hietala, Vincent M [Placitas, NM]; Hohenwarter, Gert K. G. [Madison, WI]; ...

A process for formulating non-hysteretic and hysteretic Josephson junctions using HTS materials which results in junctions having the ability to operate at high temperatures while maintaining high uniformity and quality. The non-hysteretic Josephson junction is formed by step-etching a LaAlO.sub.3 crystal substrate and then depositing a thin film of TlCaBaCuO on the substrate, covering the step, and forming a grain boundary at the step and a subsequent Josephson junction. Once the non-hysteretic junction is formed the next step to form the hysteretic Josephson junction is to add capacitance to the system. In the current embodiment, this is accomplished by addingmore » « less

Superconducting properties of magnetron sputtered Bi-Sr-Ca-Cu-O and Tl-Ba-Ca-Cu-O thin films

Conference Kampwirth, R T; Kang, J H; Gray, K E

Thin films of high temperature superconducting Bi-Sr-Ca-Cu-O and Tl-Ba-Ca-Cu-O have been made using multiple source magnetron sputtering. We will discuss preparation and annealing and how they affect the superconducting properties. The Bi-based films form in at least two compounds, a lower T/sub c/ phase with a 2212 composition and T/sub c0/ approx. 80 K and a higher T/sub c/ phase with a nominal composition of 2223 and a T/sub c/ approx. 105 K. The higher T/sub c/ phase is very difficult to form so that a complete superconducting path exists, requiring long annealing times at temperatures somewhat below the formationmore » « less
