Mössbauer study of LaNiSn and NdNiSn compounds and their deuterides

LaNiSn and NdNiSn compounds and their deuterides have been studied by variable temperature 119Sn Mössbauer spectroscopy. The hyperfine parameters obtained experimentally are in good agreement with those derived from first principle calculations. The enlargement of quadrupole splitting observed for LaNiSn after deuteration confirms the lower symmetry of electron density around tin atoms indicated by the calculation of partial Sn-p density of states (DOS). Magnetic ordering is observed at low temperature in deuterided NdNiSn.
