MULTIFILAMENTARY SUPERCONDUCTING ARTICLES AND METHODS OF FORMING THEREOF

摘要

A superconducting article is provided that includes a multifilamentary superconducting tape segment having a substrate tape, a buffer layer overlying the substrate, and filaments comprising a high temperature superconducting (HTS) material overlying the buffer layer. The filaments extend along a length of the substrate and are laterally spaced apart from an adjacent filament by a space. The multifilamentary superconducting tape segment comprises a critical current retention ratio is at least about 0.4.
