title = "Sm valence states and magnetic properties in SmBe13 and SmTi2Al20 investigated by Sm synchrotron-radiation-based M{\"o}ssbauer spectroscopy",
abstract = "Synchrotron-Radiation-based 149Sm M{\"o}ssbauer spectroscopy was applied to Sm intermetallics, SmBe13 and SmTi2Al20. Temperature dependence of the M{\"o}ssbauer parameters in SmBe13 indicate the Sm valence state is purely trivalent. SmBe13 also showed second-order Doppler shift in synchrotron-radiation-based 149Sm M{\"o}ssbauer spectroscopy. The M{\"o}ssbauer parameters obtained in SmTi2Al20 suggest that the Sm valence is fluctuating and the magnitude of the magnetic moment is reduced by hybridization between 4f and conduction electrons and/or effect of crystal electric field.",
