Optical transitions in MnGa2Se4
- 1. National Academy of Sciences of Azerbaijan, Institute of Physics (Azerbaijan)
Description
The dependence of the absorption coefficient on incident photon energy in a MnGa2Se4 single crystal has been investigated in the temperature range 110–295 K. Using group-theory analysis of the electron state symmetry and comparison of the symmetry of the energy spectrum of MnGa2Se4 and its isoelectronic analogs, a conclusion about the character of optical transitions has been drawn. It is shown that the features observed at 2.31 and 2.45 eV are related to the intracenter transitions 6A11 → 4T2(4G) and 6A12 → 4T2(4G). The 6A1 state is split by the crystal field.
