Structure and phonon density of states of supported size-selected 57FeAu nanoclusters: A nuclear resonant inelastic x-ray scattering study
Applied Physics Letters 95, (14),pp 143103/1-3 (2009)
We have measured the phonon density of states (PDOS) of isolated bcc and fcc FexAu1−x alloy nanoclusters (NCs) by nuclear resonant inelastic x-ray scattering. Drastic deviations were observed with respect to the PDOS of bulk Fe-Au alloys. Important information on the structure and thermodynamic properties of these NCs was obtained.
