Sn-119 Mossbauer spectroscopy studies of hydrides deriving from the stannide CeNiSn

The systems CeNiSnH(y) (y = 0, 1.0, and 1.8), LaNiSnH(y) (y = 0 and 2.0) and Ce(Ni(0.82)Cu(0.18))SnH(y) (y = 0 and 1.7) have been investigated by Sn-119 Mossbauer spectroscopy. This study reveals: (1) a random distribution of the H-atoms in the hydrides; (2) an increase of the quadrupole splitting Q...

Description
Summary:The systems CeNiSnH(y) (y = 0, 1.0, and 1.8), LaNiSnH(y) (y = 0 and 2.0) and Ce(Ni(0.82)Cu(0.18))SnH(y) (y = 0 and 1.7) have been investigated by Sn-119 Mossbauer spectroscopy. This study reveals: (1) a random distribution of the H-atoms in the hydrides; (2) an increase of the quadrupole splitting QS correlated with the increase of the H-content; (3) at 4.2 K the presence of a transferred magnetic hyperfine field at the Sn nuclei in the hydrides CeNiSnH(1.0), CeNiSnH(1.8) and Ce(Ni(0.82)Cu(0.18))SnH(1.7) in agreement with their magnetic properties.
