Stabilization of the high coercivity ?-Fe2O3 phase in the CeO2-Fe2O3/SiO22 nanocomposites
Original language description
We have investigated the processes leading to the formation of the Fe2O3 and CeO2 nanoparticles in the SiO2 matrix in order to stabilize the ?-Fe2 O3 as the major phase. The samples with two different concentrations of the Fe were prepared by sol?gel method, subsequently annealed at different temperatures up to 1100°C, and characterized by the Mössbauer spectroscopy, Transmission Electron Microscopy (TEM), Powder X-ray Diffraction (PXRD), Energy Dispersive X-ray analysis (EDX) and magnetic measurements.The evolution of the different Fe2O3 phases under various conditions of preparation was investigated, starting with the preferential appearance of the ? phase for the sample with low Fe concentration and lowe annaling temperature and stabilization of the major ? phase for high Fe concentration and high annealing temperature, coexisting with the most stable ? phase.
