| Abstract: | Mössbauer emission spectra of LiNbO3:57Co single crystals at 100 K in a magnetic field of 4 T show Fe3+ line intensities corresponding to a nearly Boltzmann population of the6A1g Zeeman sublevels. Supposing that this is due to a spin-lattice relaxation in the ground state, no relaxation matrix can reproduce the shape of the spectrum. We conclude that the initial populations are temperature dependent due to spin-lattice relaxation within the \(\Gamma _6 ^T \) excited doublet. |
