Abstract

The polyol process and the parameters influencing the synthesis of metal and alloy nanoparticle are discussed. Then, the synthesis strategies to obtain hard (Fe-Pt) and soft (Fe-Co) nanoparticles by using polyol process is presented. Under optimum synthesis conditions, partially ordered Fe-Pt nanoparticles with an average grain diameter of 8 nm exhibited a coercivity of 460 kA/m in the as-synthesized state. In the case of Fe-Co alloy particles, synthesis technique to prepare particles with varying Fe concentration in the size ranging between 300 and 50 nm is reported.
