Abstract: Critical temperature, Tc, and transition width, ΔTc, are two primary parameters of the superconducting transition. The latter parameter reflects the superconducting state disturbance originating from the thermodynamic fluctuations, atomic disorder, applied magnetic field, the presence of secondary crystalline phases, applied pressure, etc. Recently, Hirsch and Marsiglio (2021 Phys. Rev. B 103 134505, doi: 10.1103/PhysRevB.103.134505) performed an analysis of the transition width in several near-room-temperature superconductors and reported that the reduced transition width, ΔTc/Tc, in these materials does not follow the conventional trend of transition width broadening in applied magnetic field observed in low- and high-Tc superconductors. Here, we present a thorough mathematical analysis of the magnetoresistive data, R(T, B), for the high-entropy alloy (ScZrNb)0.65[RhPd]0.35 and hydrogen-rich superconductors of Im-3m-H3S, C2/m-LaH10 and P63/mmc-CeH9. We found that the reduced transition width, ΔTc/Tc, in these materials follows a conventional broadening trend in applied magnetic field. © 2021 IOP Publishing Ltd.
