Abstract

The Fe2+ fraction observed in the Mössbauer emission spectra of57Co:LiNbO3 and57Co:LiTaO3 exhibits both slow electronic relaxation and nonthermal populations of thems sublevels of the5Alg orbital singlet ground state at low temperatures (T<15 K) in high magnetic fields. The relaxation rates depend on temperature and on the angle ϕ between the magnetic field and the crystallographicc-axis.
