Abstract
A biaxially textured article includes a rolled and annealed, biaxially textured substrate of a metal having a face-centered cubic, body-centered cubic, or hexagonal close-packed crystalline structure; and an epitaxial superconductor or other device epitaxially deposited thereon.
Claims3
A method of preparing a biaxially textured laminate article comprising the steps of:
- a. providing a substrate having a biaxially textured Ag surface;
- b. depositing onto said surface of said substrate an epitaxial buffer template layer of ReBCO using a pulsed laser deposition technique at a temperature in the range of about 600.degree. C. to about 700.degree. C., and at an oxygen pressure in the range of about 50 mTorr to about 300 mTorr;
- and,
- c. depositing onto said buffer template layer another epitaxial layer of perovskite-like material using a pulsed laser deposition technique.
