Patent ID: 7756557

Claim:
A method of manufacturing an AC-tolerant high temperature superconductor tape with transposed filaments, comprising the steps of: depositing a first layer of high temperature superconducting material upon a buffered substrate, wherein the buffered substrate is a high temperature superconducting material having an upper edge and a lower edge along the length of the tape; creating a plurality of fully segregated striations within the first layer at an angle perpendicular to current flow, wherein the striations achieve a plurality of high temperature superconducting filaments from edge to edge; depositing an insulating layer upon the first layer between the upper and lower edges of the first layer; depositing a second layer of high temperature superconducting material having an upper and lower edge along the length of the tape upon the insulating layer and the edges of the first layer, wherein the insulating layer provides an epitaxial template for the second layer and isolates the first layer from the second layer; and creating a plurality of fully segregated striations within the second layer at an angle perpendicular to current flow and a mirror image of the striations within the first layer, wherein the striations in the second layer achieve a plurality of high temperature superconducting filaments in the second layer, and wherein the filaments of the first layer are aligned with the filaments of the second layer such that the filaments are recoupled at the upper and lower edges of the first and second layers of superconducting material.
