Raman scattering study of (K $_{x}$ Sr $_{1 - x}$ )Fe $_{2}$ As $_{2}$ ( $x$ = 0.0, 0.4)

A. P. Litvinchuk, V. G. Hadjiev, M. N. Iliev +3

Polarized Raman spectra of non-superconducting SrFe $_{2}$ As $_{2}$ and superconducting K $_{0.4}$ Sr $_{0.6}$ Fe $_{2}$ As $_{2}$ ( $T_{c} = 37$ K) are reported. All four phonon modes (A $_{1 g}$ + B$_…

Raman phonons in ReOFeAs (Re= Sm, La)

V. G. Hadjiev, M. N. Iliev, K. Sasmal +2

We report the polarized Raman spectra of undoped ReOFeAs (Re = Sm, La) collected at room temperature from $ab$ surfaces of impurity free microcrystals. The spectra exhibit sharp ph…
