Аннотация
A finite-temperature perturbation formalism is employed to study the
nonlinear processes for interactions between the discrete spin waves
(SW) in ultrathin antiferromagnetic films, taking account of both
dipole-dipole and exchange coupling between the spins. Within a
microscopic Hamiltonian approach we obtain the dominant three- and
four-magnon interactions at low temperatures, and their contributions to
the frequency shift and damping (or reciprocal lifetime) of the discrete
SW are evaluated. Numerical results applied to MnF2 are presented. (C)
