dc.description.abstract | En este trabajo se reporta la síntesis del superconductor YBa2Cu3O7-δ mediante el método no convencional de sinterización por plasma en el rango de descarga luminiscente anormal (DLA). Las muestras se sometieron a diferentes temperaturas y tiempos de sinterización. Como referencia se usó una muestra superconductora obtenida por el método convencional (horno resistivo). La caracterización estructural de estas muestras se hizo por difracción de rayos X y refinamiento con el método de Rietveld. El comportamiento superconductor se determinó mediante el análisis de las curvas de magnetización en función de la temperatura según los procedimientos experimentales de enfriado en campo magnético cero (zero field cooling, ZFC) y enfriado con campo magnético aplicado (field cooling, FC). Las muestras sinterizadas por DLA presentaron características estructurales (ortorrómbica Pmmm) y superconductoras con una temperatura crítica de Tc~ 92 K, similares a las obtenidas por el método convencional, pero con una significativa reducción en las temperaturas y tiempos, bajo un ambiente adecuado de presión en el proceso de sinterización. | spa |
dc.description.abstract | In this study we synthesized the YBa2Cu3O7-δ superconductor using the unconventional method of plasma sintering in the range of abnormal glow discharge (AGD). The samples were treated with different sintering temperatures and times. As reference we used a superconductor sample obtained by using the conventional method (resistive furnace). The structural characterization of these samples was performed by X-ray diffraction measurements and Rietveld refinements. Superconductivity behavior was determined by analyzing magnetization curves as a function of the temperature according to zero field cooling (ZFC) and field cooling (FC) experimental procedures. The samples sintered by AGD presented structural characteristics (orthorhombic Pmmm) and superconductivity with a critical temperature of Tc ~ 92 K, which were similar to those obtained by the conventional method, but with a significant reduction of temperature and time under proper pressure environment during the sintering process. | eng |
