Abstract

The hyperline parameters of relatively well crystallized grelgite (Fe3S4) have been determined by Mössbauer spectroscopy on a natural greigite-smythite sample. Applied-field measurements confirm the ferrimagnetic behavior. Saturation values of the magnetic hyperfine fields are 31.8 and 33.0 T for the tetrahedral and octahedral Fe respectively. The temperature dependence implies a Curle temperature of at least 800K. In addition, the analyses of the spectra provide some information about smythite for which the spectra seem to be composed of at least three sextets.
