摘要
The generalized phonon density of states(PDOS)and the valence electron density of states(EDOS)of the amorphous Fe_(90-x)Co_(x)Zr_(10)(x=4,10 and 40)alloys were measured at the room temperature by inelastic neutron-scattering and x-ray photoemission spectroscopy,respectively.Preliminary results show that the stronger the Invar effect,the softer is the PDOS in the low-energy region and the larger is the EDOS at the Fermi energy level.The enhancement of electron-phonon interaction was suggested to explain the low-energy phonon softening observed in Invar alloys.
