All Zeeman levels of Fe 3+ ions contribute intense and narrow lines to the Mössbauer emission spectra of LiNbO 3 : 57 Co and LiTaO 3 : 57 Co in 2 T ≤ H ext ≤ 7 T at 4.2 K. To explain the electronic spin and magnetic field dependence of the line intensities irreversible processes like the decoupling of electrons from the lattice or a field‐dependent slow relaxation should be involved. The existence of a long‐lived heated localized mode is ruled out.
