(Co在水介质中，用肼还原金属盐，得到Al型结构的（Fe）Pt合金纳米粒子。Sb和Cu分别用作（Co，Pt）和（Fe，Pt）体系的添加剂。通过在水/正己烷两相介质中一步合成得到油胺包覆的CoPt溶胶。在粉末中研究了向L1（0）相的转化。(c)2004 Elsevier B. V.保留所有权利。
(Co,Fe)Pt alloy nanoparticles of Al-type structure were obtained by reduction of metallic salts by hydrazine in aqueous medium. Sb and Cu were used as additives for the (Co,Pt) and (Fe,Pt) systems, respectively. Sols of CoPt particles capped with oleylamine were obtained in one step by achieving the synthesis in an H2O/hexane two-phase medium. Conversion to an L1(0) phase was investigated in powders.
