Patent Number: 6,251,834

Title: Substrate materials

Abstract: The invention provides an improved substrate for growing layers of oxide superconductor materials for use in high current engineering applications. The invention also provides superconducting laminates based on the inventive substrates, and processes for the manufacture thereof. The substrate includes an alloy layer that is formed of either a cube-textured FeNi alloy containing about 47% Ni to 58% Ni, or (b) a cube-texture Ni--Cu alloy in the composition range 41% Ni to 44% Ni. The substrate may further include an oxide buffer layer covering a surface of the alloy layer.
