Abstract

We present our latest results on the growth of chemical solution deposited YBa₂Cu₃O₇ - BaZrO₃ nanocomposites on metallic substrates. All chemical ^TFAYBCO-BZO/^MODCZO/^ABADYSZ/SS tapes with J_c(77K,sf) = 1.7 MA/cm² have been achieved with weaker field dependence of J_c than that of standard ^TFAYBCO tapes. Angular resolved measurements show isotropic enhancement of vortex pinning due to the presence of randomly oriented BZO nanoparticles in the YBCO matrix. Chemical routes are thus a promising way to efficiently increase vortex pinning in coated conductors and improve their capabilities for high field applications.
