✦ Synopsis

Deposition of (Y 2 BaCuO 5-0.5 nm /YBa 2 Cu 3 O 7Àx$15 nm ) • N multilayer films on rolling-assisted biaxially textured Nialloy (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 YBa 2 Cu 3 O 7Àx -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.
