Abstract

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.

Key words: FePt nanoparticles, Monolayer film, Langmuir-Blogett technology
