Abstract: A mixture of Fe₂O₃ and TiO₂ oxides has been mechanically milled to form TiFe₂O₄ spinel phase. X-ray diffraction pattern of the as-milled mixture shows the presence of both Fe₂O₃ and TiO₂ phases. The broadening of the diffraction peaks and the decrease of their relative intensity are due to the grain size reduction and accumulation of internal strains. Annealing at 750°C leads to an increase of the Fe₂O₃ peaks intensity and the reduction of TiO₂ amount suggesting a possible diffusion of Ti into Fe₂O₃ crystal lattice to form Fe_2-xTixO₃ compound. The saturation magnetisation (Ms) drops from 2.6 emu/g for the as-milled mixture to 0.8 emu/g after annealing.
