Abstract

¹⁴⁹Sm and ⁵⁷Fe nuclear resonant inelastic scattering (NRIS) measurements were carried out on SmFe ₄P ₁₂, SmFe ₄As ₁₂ and SmFe ₄Sb ₁₂. A clear dip structure of the ⁵⁷Fe NRIS spectrum was found in SmFe ₄P ₁₂, which was not clearly observed for SmFe ₄As ₁₂ and SmFe ₄Sb ₁₂. On the other hand, the line width of the phonon excitation in the ¹⁴⁹Sm NRIS spectrum increases with increasing the ionic radius of the pnictogen. These findings imply that the hybridization between the Sm and Fe phonon modes is correlated to changes in the ionic radius of the pnictogen.
