Faulty evidence for superconductivity in ac magnetic susceptibility of sulfur hydride under pressure [PDF]

open access: yesNational Science Review 9: nwac086, 2022, 2021
It is generally believed that sulfur hydride under high pressure is a high temperature superconductor. In National Science Review 6, 713 (2019) Huang and coworkers reported detection of superconductivity in sulfur hydride through a highly sensitive ac magnetic susceptibility technique and an unambiguous determination of the superconducting phase ...
