| 摘 要： | FePt纳米粒子由于具有高的矫顽力而成为高密度垂直磁记录材料的研究热点之一，均匀有序排布的FePt纳米粒子薄膜将有利于提高磁记录介质的记录密度，因此，如何使FePt纳米颗粒均匀有序地排布是当前需要解决的关键问题之一，很多研究小组利用磁控溅射、自组装和电沉积等方法对FePt纳米颗粒的均匀分布进行了详细的研究，

| Abstract: | The monolayer film of FePt nanoparticles with the mean size about 4 nm was fabricated on a silicon substrate by the Langmuir-Blodgett(LB) technology. The properties of the monolayer film were characterized by π-A isotherms, atomic force microscope(AFM) and small-angle X-ray diffraction. The results showed that the monolayer of FePt nanoparticles has a smooth surface and a dense structure as shown by the AFM image. Small-angle X-ray diffraction(SXRD) measurement of multilayer structure for the FePt nanoparticles indicated that the superlattices consist of well-defined smooth layers. |
