Evidence for Three Fluctuation Channels in the Spin Resonance of the Unconventional Superconductor CeCoIn5
(2012) In Physical Review Letters 109(23).- Abstract
- Polarized inelastic neutron scattering under a magnetic field is used to get a microscopic insight into the spin resonance of the heavy fermion superconductor CeCoIn5. The resonance line shape is found to depend on the neutron polarization: Some of the spectral weight is common to the two polarization channels while the remaining part is distributed equally between them. This is evidence for the spin resonance being a degenerate mode with three fluctuation channels: A Zeeman split contribution and an additional longitudinal mode.
