Abstract

The milling of spinel-related Ti-doped Li0.5Fe2.5O4 for different times is studied with XRD, Mossbauer spectroscopy and magnetic measurements. Milling converts the material to Li-Ti-doped alpha-Fe2O3 nanocrystalline particles via an intermediate gamma-LiFeO2-related phase. The role played by the dopant Ti-ion in the process is emphasized.
