Enhanced flux pinning and critical currents in Y[Ba.sub.2][Cu.sub.3][O.sub.7-[delta]] films by nanoparticle surface decoration: extension to coated conductor templates

The artificial nanoparticle surface decoration technique was extended to the surfaces of technologically important biaxially textured metallic substrates to describe improvements in flux pinning properties of YBCO films subsequently grown by pulsed laser deposition (PLD). The findings offer insight into the effectiveness of interface engineering to induce flux pinning defects in the high temperature superconductor (HTS) matrix.
