Multifilament superconductor having reduced AC losses and method for forming the same

摘要

A high temperature superconductor structure including: a substrate on which at least one buffer layer is deposited, a superconductor layer on the buffer layer, the superconducting layer composed of superconductor material that forms at least two substantially parallel superconductor filaments that continuously extend along the length of the substrate wherein at least two superconductor filaments are separated from each other by at least one insulating strip wherein the insulating strip continuously extends along the length of the substrate and is composed of insulating material with a resistivity greater than about 1 mΩcm. Also disclosed are methods of producing high temperature superconductors.
