Comment on “Room-temperature superconductivity in a carbonaceous sulfur hydride” by Elliot Snider et al.
J. E. Hirsch
Abstract
Abstract Room temperature superconductivity has been reported for a carbonaceous sulfur hydride (CSH)under high pressure by Snider et al [1]. The paper reported sharp drops in ac magnetic suscep-tibility as a function of temperature for six different pressures, that were interpreted as signalingsuperconducting transitions. Recently, two of the authors of ref. [1] posted in ref. [2] the underlyingdata for the ac magnetic susceptibility of CSH reported in ref. [1]. Here I provide an analysis ofthese underlying data. The results of this analysis call into question the generally accepted viewthat carbonaceous sulfur hydride is a room temperature superconductor
