Structural and magnetic properties of Fe2O3 nanoparticles dispersed over a silica matrix
Article Abstract:
The structure and the magnetic properties of a series of Fe2O3-SiO2 nanocomposites prepared by sol-gel method and submitted to thermal treatments in the temperature range 300-900 degrees Celsius, were investigated using a multitechnique approach. Findings indicate that the saturation magnetization lowers in the samples with higher Fe2O3 content. Interparticle interactions also contribute to the decrease as shown by fitting magnetic susceptibility values versus temperature.
