The generalized phonon density of states (PDOS) and the valence electron density of states (EDOS) of the amorphous Fe90-xCoxZr10 (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.
