High-Temperature Superconductivity in Hydrides: Experimental Evidence and Details

High-Temperature Superconductivity in Hydrides: Experimental Evidence and Details

Since the discovery of superconductivity at 200 K in H3S [1] similar or higher transition temperatures, Tcs, have been reported for various hydrogen-rich compounds under ultra-high pressures [2]. Superconductivity was experimentally proved by different methods, including electrical resistance, magnetic susceptibility, optical infrared, and nuclear resonant scattering measurements. The crystal structures …
