    An investigation on the variation of the particle size, particle density and its relation to the hard magnetic properties of FePt nanoparticles with respect to substrate surface morphologies and substrate temperatures was performed. At a substrate temperature below 573 K, densely dispersed FePt nanoparticles with a particle density of 1012 cm -2 were obtained. It was found that for obtaining well-oriented and well-isolated L10-FePt nanoparticles with large coercivity, substrate temperatures between 623 and 823 K were necessary.
