Abstract

We report In and Co Knight shift results for the heavy fermion superconductor CeCoIn5 in the normal state up to 8.0 T with the magnetic field parallel to the [001] crystal axis. Upon increasing the field from 5.0 T, the Knight shifts of both the In(1) and the Co sites are gradually suppressed, being consistent with the emergence of a Landau Fermi Liquid state from a Non Fermi Liquid state. We discuss the field dependence of the quantum criticality of CeCoIn5.
