Author(s): A. Charnukha, D. Pröpper, T. I. Larkin, D. L. Sun, Z. W. Li, C. T. Lin, T. Wolf, B. Keimer, and A. V. Boris We report the complex dielectric function of high-quality A Fe 2 As 2 , ( A =Ca, Sr, Ba) single crystals with T N ≈150 K, 200 K, and 138 K, respectively, determined by broadband spectroscopic ellipsometry at temperatures 10≤ T ≤300 K and wave numbers from 100 cm −1 to 52000 cm −1 . In CaFe 2 As 2 we identify the opt... [Phys. Rev. B 88, 184511] Published Fri Nov 22, 2013
