Abstract


Se sintetizaron nanopartículas de dos compósitos del sistema Fe2O3-Ni1-xZnxFe2O4, mediante el método de coprecipitación, empleando agitación por sonicación y burbujeo de nitrógeno. Los nanocompósitos sintetizados fueron caracterizados mediante: difracción de rayos-X, espectroscopia infrarroja por transformada de Fourier, espectroscopia de rayos-X por dispersión de energía, microscopía electrónica de transmisión y magnetometría de muestra vibrante. Ambos nanocompósitos presentaron las dos fases cristalinas correspondientes a las estructuras romboédrica y cúbica espinela, características de la hematita y las ferritas cúbicas. El parámetro de celda unidad (a) de la fase espinela aumenta con el incremento de la concentración de cationes Zn2+, indicando que se produce una expansión de la red. Los dos nanocompósitos están formados por nanopartículas aglomeradas, con formas irregulares y tamaños medios inferiores a 10 nm. Las medidas de magnetización en función del campo magnético aplicado sugieren que, a temperatura ambiente, las partículas de los dos nanocompósitos se encuentran en el régimen superparamagnético.
