We report results of an investigation of the temperature dependence of themagnon and phonon frequencies in NiO. A combination of Brillouin - Mandelstamand Raman spectroscopies allowed us to elucidate the evolution of the phononand magnon spectral signatures from the Brillouin zone center (GHz range) tothe second-order peaks from the zone boundary (THz range). Thetemperature-dependent behavior of the magnon and phonon bands in the NiOspectrum indicates the presence of antiferromagnetic (AF) order fluctuation ora persistent AF state at temperatures above the Neel temperature (T=523 K).Tuning the intensity of the excitation laser provides a method fordisentangling the features of magnons from acoustic phonons without theapplication of a magnetic field. Our results are useful for interpretation ofthe inelastic-light scattering spectrum of NiO, and add to the knowledge of itsmagnon properties important for THz spintronic devices.
