| description |
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 900C. 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 the transition to the superconducting state was obtained below a temperature of 90K. The morphological characterization was performed by scanning electron microscopy (SEM) and elemental analysis by means of dispersive energy spectroscopy (EDX) measurements. The electrical study was performed by means of voltage measurements as a function of the current at room temperature and subsequent calculation of the volumetric resistivity. The study of the percolative effect was carried out by calculating the critical volume and the critical exponents in each one of the insulating and conductive phases, using the Kussy model [1] and the semi-classical non-linear response model Random Resistor cum Tuning Bond Network (RRTN)[2], by contrasting critical exponents with those found in the literature |

La caracterización estructural de los compuestos sintetizadosse realizó por medio de difracción de rayos X, usando el método de re namiento Rietveld, realizando un análisis cuantitativo de fases en volumen. Los resultados obtenidos permiten con rmar que los dos materiales (GBCO/SGSO) son estables químicamente, coexistiendo en un mismo volumen a 900 C. También se encontró, mediante medidas de magnetización, que el GBCO contenido en cada uno de los diferentescompósitos, conservó sus propiedades superconductoras, ya que se obtuvo la transición al estado supercon- ductor por debajo de una temperatura de 90 K. La caracterización morfológica se realizó mediante medidas de microscopia electrónica de barrido (SEM) y análisis elemental mediante medidas de espectroscopia de energía dispersiva (EDX). El estudio eléctrico se realizó mediante medidas de voltaje en función de la corriente a temperatura ambiente y posterior cálculo de la resistividad volumétrica. El estudio del efecto percolativo se llevó a cabo mediante el cálculo del volumen crítico y de los exponentes críticos en cada una de las fases aislante y conductora, usando el modelo de Kussy [1] y el modelo de respuesta no lineal semi clásica Random Resitor cum Tunelling bond Network (RRTN) [2] contrastando los exponentes críticos, con los encontrados en la literatura.application/pdfspaspaUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ciencia_en_desarrollo/article/view/4377/pdfDerechos de autor 2018 CIENCIA EN DESARROLLOhttp://purl.org/coar/access_right/c_abf2Ciencia En Desarrollo; Vol. 9 No. 1 (2018): Vol 9, Núm. 1 (2018): Enero - Junio; 33-40Ciencia en Desarrollo; Vol. 9 Núm. 1 (2018): Vol 9, Núm. 1 (2018): Enero - Junio; 33-402462-76580121-7488SupercoductividadcompositoFisicaSupercoductividadSuperconductivityCompositesSynthesis, structural analysis, chemical stability, magnetic study and electric percolative effect on composite GdBa2Cu3O7−δ /Sr2GdSbO6Síntesis, análisis estructural, estabilidad química, estudio magnético y efecto percolativo eléctrico del compositor GdBa2Cu3O7−δ /Sr2GdSbO6info:eu-repo/semantics/articleInvestigación cientificahttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_2df8fbb1Montana Quintero, Nilzon001/15199oai:repositorio.uptc.edu.co:001/151992025-07-18 10:56:40.247metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co |
