Abstract
Measurements of specific heat, magnetic susceptibility, electrical resistivity, and penetration depth have been performed on CeCo In5-x Snx (0≤x≤0.24) single crystals. The suppression of superconductivity and the decrease of the specific heat jump at Tc, ΔC Tc, with increasing Sn concentration, and the power-law temperature dependence of penetration depth are consistent with impurity scattering calculated within the Abrikosov-Gorkov formalism indicating d -wave superconductivity in CeCo In5-x Snx. The non-Fermi liquid behavior [C T∼-ln T and ρ (T) ∼T] observed in the normal state in zero magnetic field is quite robust against Sn substitution (and a variety of other tuning parameters), suggesting quantum criticality involving itinerant f -electrons in this system.
