Abstract
Chemically synthesized FePt nanoparticles have many attractive features, such as their ease of synthesis, narrow size distribution, chemical stability, and potential applications in high-density data storage. The novel solveutless synthesis of FePt nanoparticles larger than 5 nm with controlled composition has been developed by using iron acctylacetonate in place of iron pentacarbonyl as an iron precursor, where the conventional solvent was not used at all. The obtained large FePt nanoparticles (6.1 ± 0.6 nm Fe36Pt 54, 5.8 ± 0.7 nm Fe44Pt56, and 5.1. ± 0.7 nm Fe49Pt51 nanoparticles) in 2D assembly were found to be thermally more stable than the small nanoparticles.
