用化学方法合成了L10FePt纳米结构。制成的材料显示了1.4Koe的胁迫场，没有进行后处理。Au的加入增加了FCT相的数量，完全消除了Fe氧化物，使材料在室温下具有高达5.8kOe的矫顽力。在Pluronic-F127存在下合成的粒子为球形，∼直径为8.7 nm，而在油酸和PVP存在下合成的粒子呈蠕虫状，宽度小于5 nm。
L10 FePt nanostructures were chemically synthesized. The as-made material revealed a 1.4 kOe coercive field, without a postannealing procedure. Addition of Au resulted in the increase of the fct phase and the complete elimination of Fe-oxides, leading to a material with up to 5.8 kOe coercivity at room temperature. The particles synthesized in the presence of pluronic-F127 are spherical with ∼8.7 nm diameter, whereas the particles synthesized in the presence of oleic acid and PVP have a wormlike shape and are less than 5 nm in width.
