We have synthesized a new superconductor ZnN y Ni 3 with T c ~3 K. The crystal structure has the same anti-perovskite-type such as MgCNi 3 and CdCNi 3. As far as we know, this is the third superconducting material in Ni-based anti-perovskite series. For this material, superconducting parameters, lower critical field H c1 (0), upper critical field H c2 (0), coherence length ξ(0), penetration depth λ(0), and Gintzburg -Landau parameter κ(0) have been experimentally determined.
