AB  - CeCo(In0.990Hg0.010)5 is a charge doped variant of the d-wave CoCoIn5 superconductor with coexistent antiferromagnetic and superconducting transitions occurring at TN=3.4 and Tc=1.4  K, respectively. We use neutron diffraction and spectroscopy to show that the magnetic resonant fluctuations present in the parent superconducting phase are replaced by collinear c-axis magnetic order with three-dimensional Ising critical fluctuations. No low-energy transverse spin fluctuations are observable in this doping-induced antiferromagnetic phase and the dynamic resonant spectral weight predominately shifts to the elastic channel. Static (τ>0.2  ns) collinear Ising order is proximate to superconductivity in CeCoIn5 and is stabilized through hole doping with Hg.
