Beitollahi, H. Golpayegani, M. Niyaeifar] In the work presented here attempt is made to investigate phase evolution and magnetic properties of Co/α-Fe2O3:1:6 (molar ratio) powder mixtures subjected to high energy milling (30h) followed by annealing in air and subsequent heat-treatment in a reducing atmosphere at 400°C for 20min. The latter process gave rise to the formation of a nanocomposoite compound composed of CoFe2O4, Fe3O4 and α-Fe phases, as evidenced by Mössbauer and XRD results. Rather high maximum magnetization Mmax (88emu/g) and reasonable iHC (1.03kOe) values were obtained for the nanocomposite sample prepared. This is possibly attributed to the existence of well exchange coupled soft and hard magnetic phases. Further, the structural-magnetic properties relationship of the various powders prepared is discussed in detail. Springer Science+Business Media, LLC, 2010 Beitollahi A.
