Pressure-induced superconductivity at 32 K in MoB.

Since the discovery of superconductivity in MgB ( ∼ 39 K), the search for superconductivity in related materials with similar structures or ingredients has never stopped. Although about 100 binary borides have been explored, only a few of them show superconductivity with relatively low . In this work, we report the discovery of superconductivity up to 32 K, which is the highest in transition-metal borides, in MoB under pressure.
