Superconductivity at 161 K in Thorium Hydride $Th{H}_{10}$: Synthesis and Properties

Dmitrii V. Semenok, Alexander G. Kvashnin, Anna G. Ivanova +7

Here we report targeted high-pressure synthesis of two novel high-$T_C$ hydride superconductors, $P{6}_3/mmc$-$Th{H}_9$ and $Fm\bar{3}m$-$Th{H}_{10}$, with the experimental critical temp…
