| Research Abstract |
The reduction of Fe and Pt salts in the polyol solution has been examined to obtain the Fe-Pt alloy fine particles with a fcc structure. The fine particles of the Fe-Pt ally with fcc structure are obtained by the reduction of Fe and Pt salts with the molar ratio Fe/Pt=2.3 at 403 K. Their Fe concentration is about 50 at %. Similar fine particles are obtained when the Fe and Pt metal salt with the molar ratio Fe/Pt>2.3 is reduced below 403 K. These results suggest that the formation of Fe-Pt alloy fine particles with the Fe concentration of about 50 at % is enhanced by the reduction in relatively both low reaction temperature and high Fe concentration solution.
