Abstract: The structural and magnetic properties of granular Fe-Al2O3 nanocomposite obtained starting from sol-gel processing are presented. Samples with nominal Fe were prepared. The conversion of Fe oxides into metallic Fe was obtained by calcination at 800 oC followed by reduction at 600oC for 2 h in H2 atmosphere.Vibrating sample magnetometry at 300 K resulted in coercivity between 400 and 630 Oe and saturation magnetization between 40 and 134 emu/g.
