Electron-magnon interaction and the electrical resistivity of Tb

Abstract

Measured and calculated values of the electrical resistivity of ferromagnetic Tb in the temperature range 1.5-50 K are presented. The theoretical electron-magnon resistivity and the magnon-electron lifetime are expressed in terms of the high-temperature spin-disorder resistivity. When the contribution of electron-phonon scattering is included, the calculated resistivity is shown to agree closely with the measured values.
