Abstract

We report superconductive iridium pnictides Ba_xIr₄X₁₂ (X = As and P) with a filled skutterudite structure, demonstrating that Ba filling dramatically alters their electronic properties and induces a nonmetal-to-metal transition with increasing the Ba content x. The highest superconducting transition temperatures are 4.8 and 5.6 K observed for Ba_xIr₄As₁₂ and Ba_xIr₄P₁₂, respectively. The superconductivity in Ba_xIr₄X₁₂ can be classified into the Bardeen-Cooper-Schrieffer type with intermediate coupling.
