摘要：

Chemical reduction of ferric acetylacetonate (Fe(acac)(3)) and platinum acetylacetonate (Pt(acac)(2)) using polyol as a reducing agent as well as an effective surfactant, has successfully yielded monodisperse FePt nanoparticles with a size of approximately 2 nm. When annealed samples were compared to FePt nanoparticles synthesized using oleic acid and oleylamine as the surfactants under identical conditions, nearly 30% increase in coercivity (H-c) was achieved with the new, simple and economic method.
