Abstract

We report the direct soft chemical synthesis and characterization of a family of face centered cubic (fcc) and partially ordered face centered tetragonal (fct) FePt nanoparticles (NPs) suitable for biomedical applications. Both fcc and partially ordered fct-FePt NPs are synthesized by employing a simple polyol method. By using polyvinyl pyrolidone (PVP) as a stabilizer in various ratios during synthesis, fcc-FePt NPs have been converted into partially ordered fct-FePt NPs at low temperature (300ËC) . The advantages of this process are its simplicity, the short reaction time, easy preparation and dispersibility of the NPs in aqueous media.
