Abstract
The present invention comprises novel materials comprising composite high-Tc superconductors which contain a dispersion of precipitates and structural defects and thereby exhibit enhanced flux pinning and enhanced critical current in the superconducting state, and novel nanophase orientation processes for their preparation.
Claims8
A method for producing a high temperature oxide superconductor, the method comprising the steps of:
- (a) creating thin green sheets of superconducting material and oriented, needle-like nanophase mixture;
- (b) slicing said thin green sheets perpendicular to the surface of the thin green sheet;
- (d) placing the thin green sheet slices onto a metal substrate with the needle-like nanophases oriented normal (perpendicular) to the large surface of the metal substrate;
- and
- (e) heating the thin green sheet slices to partially melt the slices onto the substrate;
- the high temperature oxide superconductor produced having a higher critical current than the high temperature superconductor without the oriented needle-like nanophase.

A method for producing a high temperature oxide superconductor, the method comprising the steps of:
- (a) creating thin green sheets of superconducting material and oriented, needle-like nanophase mixture
- (b) laminating a plurality of said thin green sheets
