Magnetic properties of TbFe6Sn6 from neutron diffraction and 119Sn Mössbauer spectroscopy

The study of TbFe6Sn6 evidences for the first time in LFe6Sn6 compounds, the occurrence of a rearrangement of the iron magnetic structure at the ordering of the Tb sublattice. The 119Sn Mössbauer spectroscopy shows a strong reduction of the hyperfine field at the ordering of the Tb sublattice caused by the variation of the transferred anisotropic contribution.
