1 recurso en línea (páginas 33-40).This document reports the synthesis of the materials Sr2GdSbO6 (SGSO) and GdBa2Cu3O7−δ (GBCO), by the reaction method in solid state and GdBa2Cu3O7−δ /Sr2GdSbO6 (GBCO/SGSO) composites in different volumetric proportions. The structural characterization of the synthesized compounds was carried out by means of X-ray diffraction, using the Rietveld refinement method, performing a quantitative analysis of phases in volume. The results obtained confirm that the two materials (GBCO / SGSO) are chemically stable, coexisting in the same volume at 9000 C. It was also found, by means of magnetization measures, that the GBCO contained in each one of the different composites, It keeps superconducting properties, as ...
