Rare-earth (RE) superhydrides have great potential as high-temperature superconductors, with recent discoveries almost achieving room-temperature superconductivity in compressed LaH 10 and YH 9 . Here, we continue to study the rare-earth hydrides by focusing on the new hydrides that the lightest element Sc and the heaviest element Lu formed under pressure. Two new superconducting hydrides ScH 3 ( T c ∼ 18.5 K at 131 GPa) and LuH 3 ( T c ∼ 12.4 K at 122 GPa) have been identified both with cubic structure by combining X-ray diffraction and electrical resistance techniques. Among all of the REH 3 , only the superconducting properties of ScH 3 and LuH 3 have been experimentally confirmed. Our current results may offer guidance to other REH 3 , which were predicted to be superconductors but have not been experimentally confirmed.
