Effects of impurities in CeCoIn5 using inelastic neutron scattering  

J. Panarin, S. Raymond, G. Lapertot and J.-M. Mignot

The influence of Nd magnetic impurities on the spin dynamics of CeCoIn5 was studied by inelastic neutron scattering. In the Nd-substituted compound Ce0.95Nd0.05CoIn5, the psin resonance peak (observed at Omega(res) = 0.55 meV ini the pure system) is shifted to lower energies but the ratio Omega(res)/k(B)T(c) remains almost unchanged. These observations are compared with non-magnetic La-substitution.
