Effect Of The Electron-phonon Interaction On The Temperature Dependence Of The Magnetic Susceptibility Of Transition Metals
Published 1986 · Physics
Abstract Recently we pointed out the possible importance of the effect of the electron-phonon interaction on the magnetism of metals. The basic idea is that since the screening of the ion-ion interaction depends on the spin splitting of the conduction electron bands the phonon free energy becomes magnetization dependent. In this paper, we carry out quantitative applications of such a consideration in analyzing actual experimental observations on the temperature dependence of the magnetic susceptibility in transition metals. We find that the phonon effects enable us to understand quite naturally the various characteristic temperature dependencies of the magnetic susceptibility observed for Rh, Cr, Ni and Pt.
