Mossbauer study of a collinear spin density wave phase in Fe1.125Te

Abstract

In the present study, the low-temperature Mossbauer spectroscopy measurements have been earned out to investigate peculiarities of the collinear spin density wave phase in Fe1.125Te. Mossbauer spectra were collected in a temperature range from liquid helium up to room temperature. The low temperature spectra of Fe1.125Te have shown a complex shape somewhat similar to that reported for Fe1.05Te. It was approximated with a set of magnetic sextets with a distribution of hyperfine fields. The obtained distribution appeared to be in a good agreement with the recent neutron diffraction studies reported.
