Towards the understanding of the SDW-phase in Nd0.05Ce0.95CoIn5
Nd0.05Ce0.95CoIn5 is a novel heavy-fermion superconductor where a spin-density wave can be field-tuned over a quantum phase transition inside its superconducting condensate. Resent inelastic neutron scattering results from our group have resolved a spin-resonance in Nd0.05Ce0.95CoIn5 that scales with the superconducting properties of CeCoIn5. Intriguingly our data hint for a scenario that this low-energy excitation is not affected by the onset of static magnetic order at 0.8 K = TN < Tc = 1.8 K. We plan to extent our successful experiment to a careful investigation of its temperature dependence and determine its transversal and longitudinal correlation lengths.
