Abstract :
In this paper, we report a chemically ordered and agglomeration-free FePt nanoparticles system, which is enabled by adding an agglomeration inhibitor. The inhibitor is so effective that gives agglomeration-free status after post-anneal under vacuum, even if it is carried out at 800/spl deg/C. This method therefore revealed magnetic properties of FePt as isolated nanoparticles.
