摘要: Using DTA, X-ray diffraction, vibrating sample magnetometry, and Rietveld refinement, we analyze the structural evolution under thermal treatment, its relation to magnetic properties, of compound formed by iron oxide particles embedded in a silica xerogel matrix. A variation refinement method is used calculate amorphous crystalline content these composites considering an initial model assumed be same composition as material modelled. We refined structure compounds using Maud program found that this can determine fractions composites. Structural changes are correlated with properties.
