- Аннотация: We apply high energy mechanosynthesis in mixtures of Y2O3 and Fe2O3 to form activated nanostructured oxide composites for subsequent temperature treatment with the aim to synthesize single phase functional Y3Fe5O12 garnet particles. Obtained at the same temperature regime but starting from structurally different precursors, garnet particles demonstrate different magnetic behavior. Mossbauer and Raman spectroscopy were applied for a comprehensive characterization on the local atomic scale the influence of the mechanochemically produced precursor’s fine structure formed at different activation duration on the structural and magnetic state of the garnet particles. X-ray diffraction and visualization of fine particles structure by SEM microscopy were supplemented. An intermediate disordered iron oxide phases and orthoferrite YFeO3 rather garnet structure formation at prolonged duration of intense mechanical activation was determined. Magnetic structure of Y3Fe5O12 formed after annealing was dependent on the degree of the oxides interaction in precursors and defects concentrated at the grain boundaries and interfaces. Both applied spectroscopies showed complementary insight into the nature of the local structural disorder at the steps of mechanosynthesis to the mechanism of fine garnet structure formation.
