Abstract

The luminescence and excitation spectra of the three-dimensional antiferromagnet CsMnF3 are investigated in the temperature range 4.2−60°K. Self-localization of magnetic excitons is observed at low temperatures. It is shown that the main reason for this self-localization is that the transfer of electronic excitation energy is two-dimensional in character, due to the specifics of the magnetic structure of the crystal.
