Abstract
Monodisperse FePt nanoparticles were successfully synthesized using the chemical polyol process. Annealing at the high temperatures is required to achieve the hard ferromagnetic behavior with L10 phase. Annealing causes the surfactant surrounding particles to be decomposed. Under such circumstances, FePt particles are agglomerated, and their size increases. In this research, NiO oxide particle with a high melting point was used for the first time as the shell around FePt core particles to prevent agglomeration. As a result, coercivity, Hc, of FePt and FePt/NiO nanoparticles after annealing at 750 °C are equal to 10 and 7 kOe, respectively.
