Pressure Induced 18 K Superconductivity and Two Superconducting Phases in CuIr2S4

Bijuan Chen, Yuhao Gu, Dong Wang +20

We report pressure-induced superconductivity in the spinel CuIr${}_2$S${}_4$ with a transition temperature ($T_{\text{c}}$) reaching \textbf{18.2 K}, establishing a new record for…
