Synthesis and characterization of cobalt nanoparticles by cobalt-acetate

摘要：

　　In this study,cobalt nanoparticles with an average size of 16 nm were synthesized using cobalt-acetate as precursor.Besides oleylamine and oleic acid,sodium oleate was selected as surfactants to control the size of particles.The obtained particles show cubic shape and uniformly disperse.The hysteresis curve of cubic nanoparticles detected by vibrating sample magnetometer (VSM) reveals that the coercive force Hc is 297.62 Oe and the saturation magnetization Ms is 56.55 emu/g.
