a, ΔIc versus magnetic field in chiral molecule intercalated TaS2. b, ΔIc versus field in chiral molecule intercalated TaS2, which can be resolved with a combination of odd (c) and even (d) function components. c, Phenomenological calculated field-mediated critical current differences ΔIc-odd as a function of magnetic field. d, Field-free diode component ΔIc-even as a function of magnetic field, which shows oscillation patterns (magenta). We note that there is an apparent oscillation with several peaks in the ΔIc-even versus B scan, with a Fraunhofer-like pattern. The overall amplitude of ΔIc-even decays more slowly with magnetic field than a typical Fraunhofer pattern (in which the peak amplitude scales with 1/B), but fits well with a non-uniform supercurrent distribution favouring an edge-state transport54,55,56. The dashed lines are fitting of a Fraunhofer pattern with uniform current distribution (red) or with edge current distribution (blue).
