Abstract: We consider the electron–phonon interaction in the framework of dynamic spin-fluctuation theory and obtain an expression for the self-energy part that depends explicitly on the spin fluctuations and lattice vibrations. We illustrate the theoretical results with the example of iron. We show that the effect of phonons on temperature dependence of the magnetic characteristics of metals is appreciable but not as large as in the static single-site approximation of the spin-fluctuation theory and spin dynamics using classical Hamiltonians.
Keywords: spin fluctuation, phonon, magnetization, magnetic susceptibility, local magnetic moment, temperature dependence, ferromagnetic metal.
