| Abstract: | Nontoxic cobalt acetate tetrahydrate was used as a precursor to prepare cobalt nanoparticles of 8–200 nm in average diameter by thermal decomposition. The different combinations of trioctylphosphine, oleylamine and oleic acid were added as surfactants to control the particle size. These combinations resulted in the particles with saturation magnetization and coercive force ranging from 55.0 to 100.1 emu/g and from 0 to 459.3 Oe, respectively. |
