Abstract

Raman scattering by four magnons in antiferromagnets is studied. It is shown that the excited-state exchange mechanism resulting in two-magnon scattering at the same time gives four-magnon scattering as well. The intensity and line shape of this scattering is computed numerically for simple cubic systems. The agreement with experimental data is fairly good for KNiF3, if magnon-phonon interaction is taken into account.
