Description

Optical absorption spectra of MnGa2Se4 (S24 ph. gr.) single crystals have been investigated in 110-295 K temperature range. By the using of group-theoretical analyses for compounds crystallized in S24 space group and by comprising with izoelectron analogies it was shown that the minimal optical transitions localize in the centre of Brillouin zone. The features in low energy region at 2.31 and 2.43 eV are connected with intracenter transitions from splitting by crystal field states. It was shown that the contribution to the crystal splitting what is due to difference of pseudopotentials of cation sublattice atoms privileges the contribution due to tetragonal distortion
