It was the first metal superhydride to be theoretically predicted,[2][3] synthesized,[4] and experimentally confirmed[5] to superconduct at near room-temperatures.
[6][7] Since its discovery in 2019,[5] the superconducting properties of LaH10 and other lanthanum-based superhydrides have been experimentally confirmed in multiple independent experiments.
[8][9][10][11] The compound exhibits a Meissner effect below the superconducting transition temperature.
[13] Further reports indicate Tc is increased with nitrogen doping,[14] and decreased with the introduction of magnetic impurities.
[16] A similar compound, lanthanum boron octahydride, was computationally predicted to be a superconductor at 126 K (−147 °C; −233 °F) and pressure 50 gigapascals (7.3×10^6 psi).
