摘要

The detailed optical properties of BaFe_2As_2 have been determined over a wide frequency range above and below the structural and magnetic transition at T_N≈138 K. A prominent in-plane infrared-active mode is observed at 253 cm~(-1) (31.4 me V) at 295 K. The frequency of this vibration shifts discontinuously at T_N; for T
