The authors report the time-reversal symmetry breaking superconductivity in the thin-flake kagome material RbV3Sb5, manifesting primarily as an unconventional form of hysteresis that is not observed in CsV3Sb5. They also observe reentrance of superconductivity during an in-plane field-sweeping process at 400 mK.
