Abstract

The temperature dependence of the hyperfine parameters of thulium iron garnet (Tm3Fe5O12) powder was studied from 90 to 550 K using169Tm and57Fe Mössbauer spectroscopy (MB). The spectra were analyzed by least mean square fits to the transmission function. The temperature dependence of the magnetic fields of the thulium nuclei is well described by the mean field model. The coupling constants between the magnetic lattice occupied by the thulium atoms and the magnetic lattices occupied by the iron atoms were derived.
