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.
