We report the synthesis of CaMn0.9Mo0.1O3 manganite by glow discharge (GD) plasma treatment under Argon-Air atmosphere. The morphological, structural and magnetic properties were evaluated by scanning electron microscopy (SEM), X-ray diffraction (XRD) and magnetization measures. The results from these measures reveal that the properties of GD synthesized manganite are similar to that exhibited by CaMn0.9Mo0.1O3 produced by conventional resistive furnace. The Rietveld analysis of XRD patterns performed at room temperature show that the samples crystallize in orthorhombic structure of Pnma (62) space group. The magnetization curves as a function
of temperature show two inflection points related to paramagnetic-antiferromagnetic and structural transition. The GD treatment produces a compound with similar properties, reducing the time and energy consumption in comparison with conventional synthesis route by using resistive furnace.

En este trabajo reportamos la síntesis de la manganita CaMn0.9Mo0.1O3 empleando plasma de descarga luminiscente en atmosfera de argónaire.
Se evaluaron las propiedades morfológicas, estructurales y magnéticas a través de microscopía electrónica de barrido (MEB), difracción de rayos X (DRX) y medidas de magnetización. Los resultados de éstas medidas revelan que las propiedades de la manganita CaMn0.9Mo0.1O3 sintetizada por descarga luminiscente son similares a las propiedades de la misma producida en horno resistivo convencional. El análisis Rietveld de los patrones de DRX tomados a temperatura ambiente revelan que la muestra cristaliza en el grupo espacial Pnma (62) ortorrómbica. Las curvas de magnetización en función de la temperatura muestran dos puntos de inflexión que evidencian una transición paramagnética-antiferromagnética y una transición estructural. El tratamiento por descarga luminiscente produce un compuesto con propiedades similares, reduciendo el tiempo y consumo energético en comparación con la producción del mismo material
usando horno resistivo.
