概要

The electron-phonon interaction and the electron-magnon interaction in ferromagnetic nickel below room temperature are investigated by a realistic model. The Fermi vectors, the Fermi velocities and the wave functions are determined by the APW method. The phonon spectrum is calculated by the Born-von Karman model. The matrix elements of the electron-phonon interaction are evaluated by the single site approximation, which was applied to Mo with success. On the other hand, the matrix elements of the electron-magnon interaction are derived by a simple phenomenological model. The theoretical result on the electrical resistivity due to the electron-phonon interaction is found to be in reasonable agreement with experiment. The theoretical value of the electron-phonon mass enhancement factor is also reasonable. The electron-magnon interaction does not seem to make an important contribution to the resistivity of nickel below room temperature.
