摘要：

The systems CeNiSnHy (y = 0, 1.0 and 1.8), LaNiSnHy (y = 0 and 2.0) and Ce(Ni0.82Cu0.18)SnHy (y = 0 and 1.7) have been investigated by Sn-119 Mossbauer spectroscopy. This study reveals: (i) a random distribution of the H-atoms in the hydrides; (ii) an increase of the quadrupole splitting QS correlated with the increase of the H-content; (iii) at 4.2 K the presence of a transferred magnetic hyperfine field at the Sn nuclei in the hydrides CeNiSnH1.0, CeNiSnH1.8 and Ce(Ni0.82Cu0.18)SnH1.7 in agreement with their magnetic properties.
