Abstract

In this article, we present recent developments in the metal-organic chemical vapor deposition (MOCVD) route to coated conductor fabrication made at SuperOx. Two new buffer layer architectures on nonmagnetic Ni-Cr-W biaxially textured substrates are described. With the use of these architectures we have achieved critical currents in the range of 100-140 A/cm-width for the fully MOCVD produced coated conductors on Ni-Cr-W in the reel-to-reel mode. We have also demonstrated over 10-m-long MOCVD-high temperature superconductor tapes on the ion beam assisted deposition templates with Ic exceeding 300 A/cm-width.
