Two-phonon processes in Heisenberg ferromagnet

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Abstract

Using the method of double-time retarded Green function, an expression for the spin energy spectrum including the contributions of one-phonon and two-phonon processes has been derived. Calculations have been performed using the spin wave approximation. The broadening of the energy level is roughly estimated in a peculiar case.
