| Outline of Final Research Achievements |
Fe-Ni hydroxide nanoparticles with Fe compositions ranging between about 10 and 90 at% were successfully synthesized using polyol by adjusting reaction conditions. Subsequent reduction-annealing of the above polyol-derived particles with 13-56 at% Fe at 400°C resulted in the synthesis of fcc Fe-Ni alloy nanoparticles. The Fe composition of fcc Fe-Ni alloy nanoparticles was evaluated to be close to those of Fe-Ni hydroxide nanoparticles before reduction annealing. In addition, it was suggested that Fe-Ni alloy nanoparticles with L10-type structure is obtained by reduction annealing of Fe-Ni hydroxide nanoparticles with about 51 at% Fe at 300°C.
