Abstract

We have observed 3+ excitations by Raman scattering in KNiF3 at 1270 cm-1 (17.9J), and in NiO at 2800 cm-1 (18.9J). These excitations are identified as four-magnon excitations by agreement of the peak frequencies with calculated values, and in the case of NiO by the temperature shift. Scattering by four magnons is the highest-order nonresonant Raman scattering yet observed. The excitation of four magnons is interpreted in terms of excited-state propagation effects.
