Abstract

We present a new reel-to-reel method for growth of high temperature superconducting (FITS) films by reactive co-evaporation on flexible metal tapes. We have demonstrated proof of principle for this method with a small laboratory-scale setup using 8 cm long tape pieces. YBa₂Cu ₃O_7-8 is deposited on ion-beam assisted deposition textured MgO layers on top of flexible polycrystalline metal tapes. Critical current densities at 75.5 K of over 2 MA/cm² have been achieved in FITS films with over 2 Ilm in thickness, yielding a self field critical current of 450 A/cm-width. A 4.5 um thick film had a self field critical current of 590 A/cm. We discuss some practical possibilities for manufacturing of superconducting wire using this process and present new areas of research that are still needed.
