Superconductivity-induced Phonon Renormalization on NaFeCoAs
Y. J. Um, Yunkyu Bang, B. H. Min +2
We report a study of the lattice dynamics in superconducting NaFeAs (Tc = 8 K) and doped NaFe0.97Co0.03As (Tc = 20 K) using Raman light scattering. Five of the six phonon modes exp…

Similar zone-center gaps in the low-energy spin-wave spectra of NaFeAs and BaFe2As2
J. T. Park, G. Friemel, T. Loew +10
We report results of inelastic-neutron-scattering measurements of low-energy spin-wave excitations in two structurally distinct families of iron-pnictide parent compounds: Na(1-δ)F…

Raman Scattering Study of the Lattice Dynamics of Superconducting LiFeAs
Y. J. Um, J. T. Park, B. H. Min +4
We report an investigation of the lattice dynamical properties of LiFeAs using inelastic light scattering. Five out of the six expected phonon modes are observed. The temperature e…
