Castellanos Román Física, Astronomía y Matemáticas short range order diffuse scattering Electron diffraction lithium cobalt niobium oxides Synthesis of compounds belonging to the system Li3NbO4-CoO has been obtained by a solid state reaction, the products are appropriately described by the formula Li(3-3x)Co4xNb(1-x)O4; 0 < x < 1.These new compounds have been studied in their diffraction features. Their electron diffraction patterns are characterized by the existence of a well defined diffuse intensity distribution in addition to sharp Bragg reflections of a rock salt type structure. This has been attributed to the presence of atomic short range order in the structure. As the amount of Co2+ ions increases in the structure, the amount of grains which produces diffuse scattering becomes larger therefore, we propose that the presence of Co2+ drives local spatial cation distribution which would rise electron diffuse scattering. An explanation, in terms of a modulated structure, has been put in advance depicting a probable atomic arrangement to explain the detected short range order. 2005 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57063912 https://www.redalyc.org/journal/570/57063912/ https://www.redalyc.org/journal/570/57063912/html/ https://www.redalyc.org/journal/570/57063912/57063912.epub https://www.redalyc.org/journal/570/57063912/movil en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
