我们描述了高磁性铁纳米粒子的合成使用一种新型的表面活性剂，β-二酮。我们已经生产出6纳米的铁纳米颗粒，其饱和磁化强度异常高，超过散装铁值的80%。此外，我们测得的粒子磁化率为14（MKS单位），这远远高于微米级球形粒子的可能值。这些特性将允许形成可以通过磁场高度结构化的复合材料。(C)2004 Elsevier B. V.保留所有权利。
We describe the synthesis of highly magnetic iron nanoparticles using a novel surfactant, a beta-diketone. We have produced 6 nm iron nanoparticles with an unusually high saturation magnetization of more than 80% the value of bulk iron. Additionally, we measured a particle susceptibility of 14 (MKS units), which is far above the value possible for micron-scale spherical particles. These properties will allow for formation of composites that can be highly structured by magnetic fields. (C) 2004 Elsevier B.V. All rights reserved.
