Patent ID: 8682406

Claim:
A superconductor structure comprising: a substrate on which at least one buffer layer is deposited, said substrate having a length and a width, wherein the substrate has a dimension ratio of not less than about 10 2 ; a superconductor layer on said at least one buffer layer, said superconducting layer consisting of superconductor material that forms at least two substantially parallel superconductor filaments that continuously extend along the length of said substrate; wherein the at least two superconductor filaments are separated from each other by a gap in which at least one insulating strip is deposited, the at least one insulating strip having a first and second surface opposite each other, said first surface overlying said buffer layer and said second surface being substantially free of said superconductor material, the insulating strip being disposed exclusively between the at least two superconductor filaments; wherein the at least one insulating strip continuously extends along the length of said substrate and is comprised of insulating material with a resistivity greater than about 1 mΩcm; and at least one stabilizing layer overlying the superconductor layer having a thickness of at least 5 microns; wherein the stabilizer layer does not directly contact the insulating strip to couple the at least two superconductor filaments.
