Abstract Mössbauer spectra of LiNbO3:Fe(III)-single crystals at various external fields and temperatures are least-squares fitted using a static spin-Hamiltonian and appropriate relaxation matrices. An electronic secular approximation is used to reduce the number of the relaxation matrix elements. The results forH ext=0 cannot be explained by a dynamical spin-Hamiltonian. The relaxation frequency for the spectra withH ext=1.5 and 3 T is independent of energy and proportional toT 2, thus excluding a direct process.
