N2 - Low temperature synthesis of equiatomic FePt alloy nanoparticles with the FCC structure was carried out by the polyol process in the presence of NaOH at above 383 K. The Pt content in the FePt alloy particles decreased with decreasing reaction temperature and equiatomic FCC-FePt alloy nanoparticles were successfully obtained at 383 K. When the FCC-FePt alloy nanoparticles synthesized at 383 K were annealed at 573 K, a partially ordered phase with the L10 structure was observed. For comparison, FCC-FePt alloy nanoparticles were synthesized at 468 K without adding NaOH. Results showed that the degree of atomic ordering of the sample synthesized at 383 K with the addition of NaOH was higher than those obtained at 468 K after annealing at low temperatures. Thus, it is concluded that the temperature employed during the synthesis of FCC-FePt alloy nanoparticles affects the ordering transformation temperature.
