Abstract

Deposition of (Y₂BaCuO_{5-0.5 nm}/YBa₂Cu ₃O_{7-x∼15 nm}) × N multilayer films on rolling-assisted biaxially textured Ni-alloy (RABiTS^TM) substrates was investigated, as a new candidate coated conductor architecture for improved flux pinning. Significant enhancements of critical current density (J _c) > 6-fold were measured for applied magnetic fields up to 7 T at 77 K, for multilayer films compared to YBa₂Cu₃O _7-x-only films. By comparing J_c(H)/J_c(0 T) plots of films deposited on RABiTS and single-crystal substrates, the relative increase of J_c(H) from pinning was the same as measured on both substrates. This indicates the varying microstructural properties of the RABiTS templates were, on average, not adversely affecting the pinning enhancements.
