  The heavy fermion superconductor CeCoIn_5 can be tuned between
superconducting and antiferromagnetic ground states by hole doping with Cd.
Nuclear magnetic resonance (NMR) data indicate that these two orders coexist
microscopically with an ordered moment ~0.7 \mu_B. As the ground state evolves,
there is no change in the low frequency spin dynamics in the disordered state.
These results suggest that the magnetism emerges locally in the vicinity of the
Cd dopants.
