Direct excitation of two and three magnons is observed in midinfrared absorption and Raman scattering spectra of α-Fe₂O₃ crystals. These polarization characteristics and the spectra themselves are shown to be understood from group-theoretical point of view. The microscopic mechanism of three-magn...
