| contents | Relation between microstructure and superconducting properties in a-axis 123 films and superlattices M. E. Gómez C. Ballesteros J. I. Martín M. Vélez J. L. Vicent P. Prieto Física, Astronomía y Matemáticas A-axis oriented superconducting EuBa2Cu3O7 films and EuBa2Cu3O7/PrBa2Cu3O7 superlattices have been grown by sputtering on (100) SrTiO3 substrates. Structural analysis by high resolution transmission electron microscopy and X ray diffraction has been performed. Both kind of samples are well oriented with the c-axis parallel to the substrate plane, the structure at the boundaries is highly coherent and, in the superlattices, high angle X-ray satellite peaks are observed. The presence of PrBa2Cu3O7 layers in the superlattices induces a reduction in the superconducting transition temperature that can be attributed to a charge redistribution process in the CuO2 planes, which in this a-axis orientation belong simultaneously to insulating and superconducting layers 1999 artículo científico 1665-3521 https://www.redalyc.org/articulo.oa?id=94200953 en http://www.redalyc.org/revista.oa?id=942 Superficies y vacío application/pdf Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales A.C.
