A great increase in the superconducting properties has been observed at high temperatures and magnetic fields parallel to the YBa₂Cu₃O₇−x c-axis. The vortex pinning properties and the defects induced in the YBa₂Cu₃O₇−x matrix have been investigated. We show that extended defects along the c-axis, induced in the YBCO matrix by the interfacial nanostructures, lay at the origin of the improved performances.}, publisher = {American Institute of Physics}, publisher = {Applied Physics Letters, 2009, 94(17), 172513}, title = {Anisotropic c-axis pinning in interfacial self-assembled nanostructured trifluoracetate- YBa₂Cu₃O₇-x films}, author = {Gutierrez, J. and Puig, T. and Gibert, M. and Moreno Sierra, César and Romà, N. and Pomar, A. and Obradors, X.}, }
