CeCoIn5 is an anisotropic unconventional superconductor. Traces of a phase transition just below Hc2 have been seen in a variety of experiments. I will show some recent neutron scattering data which show that, with the magnetic field in the basal plane, this phase is antiferromagnetic, with an incommensurate ordering vector. This magnetic order disappears sharply at Hc2, so the antiferromagnetic state only exists when the material is superconducting; its origin, and relation to the superconductivity in this material, are open questions.
