Description:
Author(s): Sangwon Oh, A. M. Mounce, Jeongseop A. Lee, W. P. Halperin, C. L. Zhang, S. Carr, and Pengcheng Dai We have performed 75 As nuclear magnetic resonance (NMR) Knight shift measurements on single crystals of NaFe 0.975 Co 0.025 As to show that its superconductivity is a spin-paired, singlet state consistent with predictions of the weak-coupling BCS theory. We use a spectator nucleus, 23 Na, uncoupled from ... [Phys. Rev. B 87, 174517] Published Mon May 20, 2013
