Abstract: | The phonon states of iron atoms in the easy-axis aligned L1_{0}-FePt nanoparticles were investigated using 57Fe nuclear-resonant inelastic scattering. It was revealed that the phonon density of states (PDOS) in the L1_{0}-FePt has a pronounced anisotropy. To study the results from a theoretical point of view, we calculated the PDOS of the L1_{0}-FePt in the bulk state by means of the first-principles method. The results were in good agreement with the experimental results. |
