Abstract

Analogous to cuprate high-T_c superconductors, a NiP-based compound system has several crystals in which the Ni-P layers have different stacking structures. Herein, the properties of BaNi₂P₂ are reported. BaNi₂P₂ has an infinite-layer structure, and shows a superconducting transition at ∼3 K. Moreover, it exhibits metallic conduction and Pauli paramagnetism in the temperature range of 4-300 K. Below 3 K, the resistivity sharply drops to zero, and the magnetic susceptibility becomes negative, while the volume fraction of the superconducting phase estimated from the diamagnetic susceptibility reaches ∼100 vol.% at 1.9 K. These observations substantiate that BaNi₂P₂ is a bulk superconductor.
