M$"{o}$ssbauer study on the SmFe$$_2$$ hydride through $$^{149}$$Sm and $$^{57}$$Fe

Masuda, Ryo; Mitsui, Takaya; Ito, Keiji*; Kobayashi, Yasuhiro*; Kitao, Shinji*; Seto, Makoto

Nuclear resonant forward scattering of synchrotron radiation by $$^{149}$$Sm and $$^{57}$$Fe M$"{o}$ssbauer spectroscopy were applied to SmFe$$_2$$ and $$c$$-SmFe$$_2$$H$$_x$$ ($$x$$ $$_sim^{<}$$ 3), in order to study the effect hydrogen absorption to the local electronic states. The differences between the parameters of hyperfine structure of SmFe$$_2$$ and those of $$c$$-SmFe$$_2$$H$$_x$$ are discussed in connection with the modulation of local electronic states induced by the lattice expansion and the chemical effect by hydrogenation. The differences also imply the screening of the interactions between Sm and Fe by the inserted hydrogen atoms.
