Abstract
The Nd1−xCexCoIn5 alloys evolve from local moment magnetism (x=0) to heavy fermion superconductivity (x=1). Magnetic order is observed over a broad range of x. For a substantial range of x (0.83≤x≤0.95) in the temperature-composition phase diagram we find that superconductivity may coexist with spin-density wave magnetic order at the Fermi surface. We show that a delicate balance betwen superconducting and magnetic instabilities can be reversibly tuned by both the Ce/Nd ratio and magnetic field, offering a unique model electronic system.
