The Roles Of Spin Wave And Phonon In The Temperature Dependence Of Magnetization In An Itinerant Electron Ferromagnet

We show that since the phonon frequency changes with magnetization in an itinerant electron ferromagnet, phonons can have an effect on magnetization that is similar to that of spin waves. From a model numerical analysis we find that the size of the phonon effect is generally of the same order of magnitude as that of the spin wave.
