Synthesis and Stabilization of FeCo Nanoparticles

摘要

An alternative method for the synthesis of monodisperse FeCo nanoparticles of controlled size and magnetic properties has been developed via reductive decomposition of organometallic precursors in the presence of surfactants. Saturation magnetization of the particles is dependent on particle size. The particles can be made air-stable with enhanced magnetic properties by annealing at modest temperatures. The stabilized nanoparticles can be ideal building blocks for high-performance nanocomposite permanent magnets and nanostructured magnetic devices and can also be suitable for biomedical applications.
