抄録

We have synthesized a new superconductor ZnN_yNi₃ with T_c∼3 K. The crystal structure is of the same antiperovskite-type as MgCNi₃ and CdCNi₃. As far as we know, this is the third superconducting material in the Ni-based antiperovskite series and the first antiperovskite nitride superconducting material. For this new superconductor, the lower critical field H_c1(0), upper critical field H_c2(0), coherence length ξ(0), penetration depth λ(0), Ginzburg–Landau parameter κ(0), electronic specific heat coefficient γ, and Debye temperature Θ_D have been experimentally determined.
