Comment on “Nonstandard superconductivity or no superconductivity in hydrides under high pressure”

Abstract

J. E. Hirsch and F. Marsiglio in their publication [Phys. Rev. B 103, 134505 (2021)], assert that hydrogen-rich compounds under high pressures do not exhibit superconductivity. Their argument hinges on the absence of broadening of resistive superconducting transitions in applied magnetic fields. We argue that this assertion is incorrect, as it relies on a flawed analysis and a selective and inaccurate report of published data, where data supporting the authors' perspective are highlighted while data demonstrating clear broadening are disregarded.
