Abstract
The phonon states of iron atoms in the easy-axis aligned $L{1}_{0}\text{-FePt}$ nanoparticles were investigated using $^{57}\text{F}\text{e}$ nuclear-resonant inelastic scattering. It was revealed that the phonon density of states (PDOS) in the $L{1}_{0}\text{-FePt}$ has a pronounced anisotropy. To study the results from a theoretical point of view, we calculated the PDOS of the $L{1}_{0}\text{-FePt}$ in the bulk state by means of the first-principles method. The results were in good agreement with the experimental results.
