Abstract:
An investigation is made of the spectrum of magnetic excitations in an anharmonic ferromagnet in the framework of the Heisenberg model with allowance for the spin-phonon interaction of all orders in the displacements of the atoms. An exact representation is obtained for the mass operator of the two-time Green's function of the transverse spin components and an approximate expression for it is considered in the second order in the renormalized spinphonon
and spin-spin interactions.
