Abstract

A high-temperature superconducting thin-film strip conductor (HTSL-CC) includes a metal substrate, a buffer layer chemically generated thereon and grown crystallographically unrotated in relation to the metal substrate, and a chemically generated superconducting coating thereon. The HTSL-CC possesses high texturing of the buffer layer since the metal substrate has a surface roughness RMS<50 nm, and since and the buffer layer is grown directly onto its surface, without an intermediate layer, crystallographically unrotated in relation to the crystalline structure of the metal substrate.
