Abstrakt: Y2Ni7, which is pararragnetic at T=0, becomes ferromagnetic when the temperature is raised to ?7K; then at ?60K the system again makes a phase transition to paramagnetic state. We show how it is possible to understand such a behavior of an itinerant electron system if we take into account the effect of the electron-phonon interaction.
