Nanoparticles of Mn of sizes <500 ร were prepared by the ball-milling technique. The temperature dependence of the magnetic susceptibility ฯ showed systematic variation with particle size. Peaks observed in ฯ were attributed to the magnetic ordering of the oxides Mn 3 O 4 and MnO. Peaks found in โ(ฯ
The Fe 3 O 4 and CoFe 2 O 4 nanoparticles of radius 3.2 ยฑ 0.3 and 3.8 ยฑ 0.3 nm, respectively, were synthesized by the high-temperature solution phase reaction of metal acetylacetonates.
