Electron-Phonon Interaction Mechanism of Temperature Induced Ferromagnetism

Shuji Ukon, Chikako Tanaka, Keiko Kawabata and D. J. Kim

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.
