Magnetic order and superconductivity compete in most materials, but in some, they lead to novel phases and unexpected phenomena. Many forms of novel superconductivity, for example, are believed to be a result of magnetic fluctuations. We study model materials of unconventional superconductivity where magnetic field can induce novel quantum phases that feature magnetic order. These phases are theoretically not understood, and one way to study them is through doping with magnetic ions. We will dope CeCoIn5 with a few percent of Nd, and study its effect on the high-field condensate using magnetization and neutron scattering experiments.
