Description:
Author(s): Chenglin Zhang, Mengshu Liu, Yixi Su, Louis-Pierre Regnault, Meng Wang, Guotai Tan, Th. Brückel, Takeshi Egami, and Pengcheng Dai We use polarized inelastic neutron scattering (INS) to study spin excitations of optimally hole-doped superconductor Ba 0.67 K 0.33 Fe 2 As 2 ( T c =38 K). In the normal state, the imaginary part of the dynamic susceptibility, χ ′′ ( Q , ω ), shows magnetic anisotropy for energies below ∼7 meV with c -axis polarized... [Phys. Rev.
