English abstract:	In this work we report the study of chemical solution deposited (CSD) YBa2Cu3O7-δ nanostructured thin films, with diluted Ba2YTaO6 (BYTO) and BaZrO3 (BZO) impurity nanoparticles. Films were deposited on YSZ monocrystalline substrates, with a buffer layer of Cerium Zirconium Oxide (CZO), also grown by chemical method. We studied the influence of the buffer layer on superconducting properties of the films, with a secondary phase content of 10%. Films were grown with a temperature treatment consisting of a single step at 770�C. The films were characterized by X-ray diffraction, and Tc and Jc were inductively measured with a SQUID. In all X-rays diffraction patterns, presence of BaCeO3 was observed. It is known that this compound generates reactivity with YBCO, which probably caused the low Jc obtained ~ 1.3 MA/cm2 at 77K.

Las pel�culas se depositaron sobre sustratos monocristalinos de YSZ, con una capa "buffer" de �xido de cerio y circonio (CZO), tambi�n crecidas por m�todos qu�micos. Estudiamos la influencia de la capa "buffer" en las propiedades superconductoras de las pel�culas, con un contenido de fase secundaria del 10%. Las pel�culas se crecieron con un tratamiento t�rmico, consistente en un solo paso a 770�C. Las pel�culas se caracterizaron por difracci�n de rayos X, y Tc y Jc se midieron inductivamente con un SQUID. En todos los patrones de difracci�n de rayos X se observ� la presencia de BaCeO3. Se sabe que este compuesto genera reactividad con YBCO, lo que probablemente provoc� la baja Jc obtenida ~ 1.3 MA/cm2 a 77K.
