A perturbation formalism is employed to study nonlinear processes for
the interactions between the discrete spin waves in ferromagnetic films,
taking account of both dipole-dipole and exchange coupling. By contrast
with previous macroscopic theories of spin-wave interactions the dipolar
terms are treated within a Hamiltonian method to obtain results
applicable to ultrathin films. The roles of three-magnon and four-magnon
processes in the spin-wave energy shift and damping are evaluated and
numerical applications to EuO are discussed. (C) 1998 Elsevier Science
