被引用回数:1 パーセンタイル:84.42Sm synchrotron-radiation-based Mssbauer spectroscopy was performed in Sm-based intermetallics having a cubic crystal structure, SmGe, SmB, SmBe, and SmAl ( = transition metals). In spite of the difference of the local structure around the Sm sites, the observed Mssbauer spectra consist of a single line at 300 K. On the other hand, Sm L-edge X-ray absorption spectra consist of two components, suggesting Sm and Sm states. Difference of the number of the spectral components between the Mssbauer spectroscopy and X-ray absorption spectroscopy is caused by the difference of the time window in the scattering process of these measurements. Correlation between the isomer shifts in the Mssbauer spectroscopy and average Sm valence states estimated from the X-ray absorption spectroscopy exhibits a linear correlation.
