a Schematic illustration of mC-AFM measurements using a ferromagnetic substrate. b, c Current–voltage profiles for left- (b) and right-handed (c) helical supramolecules under the condition of N-pole up or S-pole up. At least 50 I–V curves were recorded and averaged for each handedness and magnetic field orientation. The standard error is adopted in (b) and (c).
