AB  - We report on morphological, structural and magnetic properties of alpha-Fe2O3 nanoparticles in an amorphous alumina matrix synthesized by aqueous combustion method. The sample was characterized by X-ray powder diffraction (XRPD), high-resolution electron microscopy (HREM) and SQUID magnetometry. XRPD study reveals the phase purity of alpha-Fe2O3 whereas HREM images show an unusual spongy structure and well-crystallized nanoparticles with a size of about 25 nm. Magnetic measurements show a high irreversibility temperature T-irr approximate to 350 K, Morin transition at T-M approximate to 210 K, increase of the magnetization below T approximate to 45 K and hysteretic behavior below T-M at 5 K and 200 K.

AB  - Starting from a nanocomposite consisting of 4 nm hematite nanoparticles embedded in a silica matrix (30 wt.% hematite) and by applying heat treatments at increasing temperatures up to 1050 degrees C, gradual formation of epsilon-Fe2O3 phase was obtained. Besides representing a new synthesis route of epsilon-Fe2O3 phase, the results obtained in this work indicate that under certain conditions hematite nanoparticles are not thermally stable. Hence, like other ferric oxide polymorphs, nanosized hematite can undergo thermally triggered, size-induced structural phase transitions. (C) 2007 Acta Materialia Inc. Published by Elsevier Ltd.
