Robust upward dispersion of the neutron spin resonance in the heavy fermion superconductor Ce1−xYbxCoIn5
The mechanism of collective magnetic excitations in unconventional superconductors remains controversial. Here, Song et al. show neutron spin resonance in a heavy fermion superconductor Ce1-xYbxCoIn5, implying magnon-like excitation rather than spin-exciton type.
