Author(s): C. Stock, C. Broholm, Y. Zhao, F. Demmel, H. J. Kang, K. C. Rule, and C. Petrovic Neutron scattering in strong magnetic fields is used to show the spin resonance in superconducting CeCoIn 5 ( T c =2.3 K) is a doublet. The underdamped resonance ( ℏ Γ =0.069±0.019 meV) Zeeman splits into two modes at E ± = ℏ Ω 0 ± α μ B μ 0 H with α =0.96±0.05. A linear extrapolation of the lower peak reaches zero e... [Phys. Rev.
