分别以乙酰丙酮铁(Fe(acac)3)和氯铂酸(H2PtCl6·6H2O)作为Fe源和Pt源,乙二醇作为还原剂和溶剂,通过多元醇还原法制备出单分散的FePt纳米颗粒,并研究了表面活性剂油酸油胺和CTAB对FePt纳米颗粒形貌和磁性能的影响.通过X射线衍射仪(XRD)、透射电子显微镜(TEM)和振动样品磁强计(VSM)对纳米颗粒进行表征.结果表明,表面活性剂油酸油胺和CTAB修饰的FePt纳米颗粒均为面心立方(FCC)结构,分散性良好,粒径分布较未使用表面活性剂时变窄；油酸油胺修饰的FePt形貌主要是球形,但是有四方形纳米结构出现；而CTAB修饰的FePt形貌有蠕虫状产生.VSM结果显示其矫顽力都趋近于零,呈现超顺磁性.
