On the interpretation of flux trapping experiments in hydrides
J. E. Hirsch, F. Marsiglio
In Ref. [1], Minkov et al. reported measurements of the magnetic moment that remains after a magnetic field is turned on and then turned off for hydride materials under high pressu…
Enormous variation in homogeneity and other anomalous features of room temperature superconductor samples: a Comment on Nature 615, 244 (2023)
J. E. Hirsch
The resistive transition width of a recently discovered room temperature near-ambient-pressure superconductor [1] changes by more than three orders of magnitude between different s…
Evidence against superconductivity in flux trapping experiments on hydrides under high pressure & On magnetic field screening and expulsion in hydride superconductors
J. E. Hirsch, F. Marsiglio
It has recently been reported that hydrogen-rich materials under high pressure trap magnetic flux, a tell-tale signature of superconductivity [arXiv:2206.14108v1]. Here we point ou…
Clear evidence against superconductivity in hydrides under high pressure
J. E. Hirsch, F. Marsiglio
The Meissner effect, magnetic field expulsion, is a hallmark of superconductivity. Associated with it, superconductors exclude applied magnetic fields. Recently Minkov et al. prese…
Absence of evidence of superconductivity in sulfur hydride in optical reflectance experiments
J. E. Hirsch, F. Marsiglio
Capitani and coworkers [1] reported that infrared optical reflectance measurements provided evidence for a superconducting transition in sulfur hydride [2] under 150 GPa pressure,…
Faulty evidence for superconductivity in ac magnetic susceptibility of sulfur hydride under pressure
J. E. Hirsch
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 detecti…
