dc.description.abstractAn efficient microwave-assisted route has been used to synthesize nanoparticles of cobalt oxide. The particles were well characterized by transmission electron microscopy (TEM) which showed that the average diameter of the particles is around 6 nm. X-ray diffraction (XRD) studies further confirmed the formation of the spinel Co<inf>3</inf>O<inf>4</inf>. Purity of the products was detected by Fourier transform infrared spectroscopy (FTIR) combined with thermal gravimetric analysis (TG/DTG). The magnetic measurements revealed a small hysteresis loop at room temperature indicating a weak ferromagnetic nature of the synthesized Co<inf>3</inf>O<inf>4</inf> nanoparticles. The magnetic moment of the particles was measured to be 4.27 ?<inf>eff</inf>. © 2010 Elsevier B.V. All rights reserved.
