Description:
Author(s): R. Mittal, M. K. Gupta, S. L. Chaplot, M. Zbiri, S. Rols, H. Schober, Y. Su, Th. Brueckel, and T. Wolf We report measurements of the temperature dependence of phonon densities of states in K 0.8 Fe 1.6 Se 2 using inelastic neutron scattering technique. While cooling down to 150 K, a phonon peak splitting ∼25 meV is observed and a new peak appears at 31 meV. The measurements support the recent Raman and in... [Phys. Rev.
