Abstract
The analysis of the mechanisms of two-magnon Raman spectra formation i n the quasi-two-dimensional antiferromagnetic crystal NH3(CH2)2NH3MnCl 4 has been done on the basis of Raman scattering and light absorption experimental data. The calculations of the magnon density of states an d polarization selection rules of the two-magnon Raman spectra are car ried out in the frame of the four-sublattice model of antiferromagneti c crystal layers.
