Electronic structures, magnetic, and superconducting properties of bcc Ni and V-doped Ni (Ni_16-xV_x)

We have investigated the electronic structures and magnetic properties of both undoped and doped bee Ni using the full-potential linearized augmented plane wave (FLAPW) band method. A ferromagnetic ground state is obtained at the equilibrium volume of bee Ni. When the system is under strain, the nonmagnetic ground state is stabilized. When the Ni is doped with V, the Ni_16-XV_X material loses its magnetic properties when x > 2. We have also discussed the possible superconducting properties of Ni₁₆-_XV_X.
