摘要
A method of forming iron-based alloy nanoparticles is disclosed. A solution containing iron salt, noble metal salt and a reducing reagent is heated, resulting in the precipitation of monodispersed nanoparticles such as FePt and FePd. The solution may also include a surfactant. After deposition, the iron-based alloy nanoparticles may be annealed in order to produce the desired crystal structure and magnetic properties. The annealed nanoparticles may comprise FePt having an L10 crystal structure and high magnetic coercivity. The magnetic iron-based nanoparticles are suitable for use in applications such as magnetic recording media, permanent magnet materials and magneto-transport systems.
