Author(s): Chenglin Zhang, Rong Yu, Yixi Su, Yu Song, Miaoyin Wang, Guotai Tan, Takeshi Egami, J. A. Fernandez-Baca, Enrico Faulhaber, Qimiao Si, and Pengcheng Dai We use inelastic neutron scattering to show that superconductivity in electron-underdoped NaFe 0.985 Co 0.015 As induces a dispersive sharp resonance near E r 1 =3.25 meV and a broad dispersionless mode at E r 2 =6 meV. However, similar measurements on overdoped superconducting NaFe 0.935 Co 0.045 As find only ... [Phys. Rev. Lett. 111, 207002] Published Tue Nov 12, 2013
