Abstract

The intrinsic electronic and magnetic properties of bare FePt nanoparticles were analyzed. The preparation of arrays of well-separated FePt nanoparticles that were free of ligands and contamination applying a combination of reactive oxygen and hydrogen plasmas was analyzed. It was found that at higher binding energies, the spectrum resembled that of pure platinum while close to the Fermi edge, it was distinct from both of the constituent metals. The negative slope of the density of state (DOS) toward the Fermi level in the fcc FePt nanoparticles was also elaborated.
