Author(s): Zhi-Guo Chen (谌志国), Luyang Wang, Yu Song, Xingye Lu, Huiqian Luo, Chenglin Zhang, Pengcheng Dai, Zhiping Yin, Kristjan Haule, and Gabriel Kotliar We report infrared studies of A Fe 2 As 2 ( A = Ba , Sr), two representative parent compounds of iron-arsenide superconductors, at magnetic fields ( B ) up to 17.5 T. Optical transitions between Landau levels (LLs) were observed in the antiferromagnetic states of these two parent compounds. Our observation of... [Phys. Rev.
