Significantly enhanced critical current density and pinning force in nanostructured, (RE)BCO-based, coated conductor.

ABSTRACT: High-temperature superconducting wires have many large-scale, niche applications such as commercial nuclear fusion as well as numerous other large-scale applications in the electric power industry and in the defense, medical and transportation industries. However, the price/performance metric of these coated conductor wires is not yet favorable to enable and realize most large-scale applications. Here we report on probing the limits of J_c (H, T) possible via defect engineering in heteroepitaxially deposited high-temperature superconducting thin-films on coated conductor substrates used for long-length wire fabrication. We report record values of J_c (H, T) and pinning force, F_p (H, T) in (RE)BCO films with self-assembled BaZrO₃ nanocolumns deposit
