Abstract:

This paper presents a description of experiments on scattering of a resonant biharmonic radiation by atmospheric and inert gases. Experimentally recorded angular–frequency spectrum of Raman light scattering by magnon polaritons is presented in the paper. This spectrogram enabled the determination of frequencies and wave vectors of the magnon polaritons involved in the light scattering process. It is shown in the experiments that signals do not change under variation of pressure inside the measurement cell from 10^–4 to 760 mm of mercury column. Some results on the role of oxygen in the process under study are also presented in the paper.
