摘要：
Inelastic neutron-scattering experiments on amorphous Fe90-xCoxZr10(x = 10 and 40) alloys have been performed. Generalized phonon densities of states (PDOS) were deduced from the measured time-of-flight spectra at room temperature. The results show that in the energy region below 17 meV, the generalized PDOS of the amorphous Fe80Co10Zr10 Invar alloy is obviously softer than that of the amorphous Fe50Co40Zr10 non-Invar alloy. It is suggested that the softening of the low-energy PDOS in Invar alloys could be attributed to an enhancement of the electron-phonon interaction.
