Title

Nature of the neutron spin resonance in CeCoIn5

Abstract

We found the resonance mode disperses upwards in Yb doped CeCoIn5. It is not clear whether it is due to Yb doping which significantly modifies the Fermi surface or it is also the case for undoped CeCoIn5. By studying the resonance we hope to clarify whether the resonance mode is due to itinerant electrons or local moments, and also shed light on the effect of Yb doping on the magnetic excitations.
