摘      要：The Meissner effect,magnetic field expulsion,is a hallmark of *** with it,superconductors exclude applied magnetic ***,Minkov et al.[***.13,3194(2022)]presented experimental results reportedly showing“definitive evidence of the Meissner effectin sulfur hydride and lanthanum hydride under high pressure,and Eremets et al.[***.35,965(2022)]argued that“the arguments against superconductivity(in hydrides)can be either refuted or explained.Instead,we show here that the evidence presented in those papers does not support the case for superconductivity in these *** with experimental evidence discussed in earlier papers,we argue that this strongly suggests that hydrides under pressure are not high-temperature superconductors.
