High-Temperature Superconductivity in Th-H System at Pressure Conditions.
Several new thorium hydrides were predicted to be stable under pressure using evolutionary algorithm USPEX, including ThH3, Th3H10, ThH4, ThH6, ThH7 and ThH10. Superconducting properties of all predicted phases were studied. The highest calculated superconducting transition temperature TC was found to be 194 K at 100 GPa for the newly predicted Fm-3m-ThH10. We discuss the potential of further investigation of new actinide-based hydrides in order to find new high-temperature superconductors.
