概要
- 論文の詳細を見る
We have synthesized a new superconductor ZnN_yNi_3 with T_c〜3K. The crystal structure is of the same antiperovskite-type as MgCNi_3 and CdCNi_3. 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.
