a Set of dI/dV spectra taken consecutively at T = 0.34 K as the perpendicular magnetic field is varied in the 0–11 T range (Va.c = 50 µV). b Zoom-in of the set shown in (a). The curves are normalized to the set-point voltage (Vb = + 25 mV). c Differential conductance values measured at the peaks maxima (E+(orange circles) and E− (brown circles)) and EF (blue triangles) in the dI/dV spectra shown in (a). d High-resolution series of dI/dV spectra taken consecutively at T = 0.34 K in the vicinity of EF (Va.c. = 30 µV).
