Abstract
The temperature dependence of the hyperfine parameters of thulium iron garnet (Tm3Fe5O12) powder was studied from 90 to 550 K using Tm-169 a nd Fe-57 Mossbauer spectroscopy (MB). The spectra were analyzed by lea st mean square fits to the transmission function. The temperature depe ndence of the magnetic fields of the thulium nuclei is well described by the mean field model. The coupling constants between the magnetic l attice occupied by the thulium atoms and the magnetic lattices occupie d by the iron atoms were derived.
