Abstract

A material termed “carbonaceous sulfur hydride” has recently been reported to be a high-pressure room temperature superconductor [Snider et al., Nature 586, 373 (2020)]. We have previously pointed out that certain anomalies observed in the published data for the ac magnetic susceptibility of this material would be cleared up once the measured raw data were made available [J. E. Hirsch, arXiv:2110.12854v1 (2021) and J. E. Hirsch, Physica C 590, 1353964 (2021) (temporarily removed)]. The measured raw data, as well as numerical values of the data presented in figures in the aforementioned paper by Snider et al., have recently been posted on the arXiv [R. P. Dias and A. Salamat, arXiv:2111.15017v1 (2021) and R. P. Dias and A. Salamat, arXiv:2111.15017v2 (2021)]. Here, we report the results of our analysis of these raw data and published data and our conclusion that the raw data are incompatible with the published data. Implications of these results for the claim that the material is a room temperature superconductor are discussed.
