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 Jc(77K,sf) = 1.7 MA/cm2 have been achieved with weaker field dependence of Jc 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.
