Abstract
The present invention relates to a method for producing a defect-containing superconducting film, the method comprising (a) depositing a phase-separable layer epitaxially onto a biaxially-textured substrate, wherein the phase-separable layer includes at least two phase-separable components; (b) achieving nanoscale phase separation of the phase-separable layer such that a phase-separated layer including at least two phase-separated components is produced; and (c) depositing a superconducting film epitaxially onto said phase-separated components of the phase-separated layer such that nanoscale features of the phase-separated layer are propagated into the superconducting film.

A method for producing a superconducting film containing defects, the method comprising:
- (a) depositing a phase-separable layer epitaxially onto a biaxially-textured substrate, wherein the phase-separable layer comprises at least two phase-separable components;
- and wherein said phase-separable components have different compositions;
- (b) achieving nanoscale phase separation of the phase-separable layer such that a phase-separated layer comprising at least two phase-separated components is produced;
- and
- (c) depositing a superconducting film onto said phase-separated components of said phase-separated layer such that nanoscale features of the phase-separated layer are propagated into the superconducting film.
