Abstract
We report the effects of La substitution on the superconducting state of the heavy-fermion superconductor CeCoIn5, as seen in transport and magnetization measurements. As opposed to the case of conventional superconductors, pair breaking by nonmagnetic La results in the depression of Tc and indicates a strong gap anisotropy. The upper critical field Hc2 values decrease with increased La concentration, but the critical field anisotropy, γ=Hc2a/Hc2c, does not change in Ce1−xLaxCoIn5 (x=0–0.15). The electronic system is in the clean limit for all values of x.
