Title: High temperature superconductors having planar magnetic flux pinning centers and methods for making the same

Abstract

Superconductor wires or layers having improved properties and methods for making the same are described. The superconducting layer includes a rare earth element-alkaline earth element-transition metal oxide having an average stacking fault density that is greater than about 0.01 nm−1, wherein two or more rare earth cations form the rare earth element. To form the superconductor layer of the present invention, a layer having a rare earth element-alkaline earth element-transition metal oxide substantially in a first crystal structure can be provided to a substrate where two or more rare earth cations form the rare earth element. The layer can then be heated at a temperature that is greater than 550° C. under oxidizing conditions to form a high-temperature superconducting layer substantially in a second crystal structure.

Niobium-titanium superconductors produced by powder metallurgy having artificial flux pinning centers

Patent Jablonski, Paul D [Madison, WI]; Larbalestier, David C [Madison, WI]

Superconductors formed by powder metallurgy have a matrix of niobium-titanium alloy with discrete pinning centers distributed therein which are formed of a compatible metal. The artificial pinning centers in the Nb-Ti matrix are reduced in size by processing steps to sizes on the order of the coherence length, typically in the range of 1 to 10 nm. To produce the superconductor, powders of body centered cubic Nb-Ti alloy and the second phase flux pinning material, such as Nb, are mixed in the desired percentages. The mixture is then isostatically pressed, sintered at a selected temperature and selected time to producemore » « less
