Abstract


Yttrium iron garnet, Y3Fe5O12 (YIG) powders were synthesized by mechanochemical processing (MCP) from Fe2O3 and Y2O3, followed by an annealing. The aim of this work was to demonstrate that MCP followed by annealing at relative low temperatures can induce the formation of nanostructured YIG. The effect of synthesis process on the final magnetic properties was also studied. The precursors mixed in a stoichiometric ratio to obtain YIG were milled at room temperature in a shaker mixer mill with a ball:powder weight ratio of 10:1. In order to achieve a single-phase of nanostructured YIG a short thermal annealing at temperatures from 700 to 1100oC was done. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize the synthesized powders. The milling process promotes the formation of a perovskite phase (orthoferrite YFeO3) independent from the milling time; garnet could only be obtained after an annealing process. The partial formation of the garnet phase was observed in mixtures milled for 5 h. In order to obtain a pure YIG, it is necessary to do a post-treatment of an annealing at temperatures of 900C, around 400 oC lower than those used to prepare the material by solid state reaction. Also, the effect of synthesis method into the magnetic behavior of the garnet was shown.
