Abstract

The phonon density of states of a pseudomorphic fcc-Fe film with ∼3 monolayers has been investigated by nuclear resonant inelastic scattering. The fcc-Fe layers are intercalated into an interface between monolayer hexagonal boron nitride and a Ni(111) substrate with a commensurate relation. The in-plane nearest-neighbor distance of the fcc-Fe film is shorter than that of uncompressed fcc-Fe precipitates in Cu by -1.8%. The compression increases the mean force constant of the fcc-Fe film, which is higher than that of uncompressed fcc-Fe precipitates by 5.8%.
