Kondo scattering versus YSR energy. a Selected dI/dV spectra of different MnPc–NH3 complexes ordered according to the YSR energy (50 mV, 200 pA, 500 μVrms). Spectra are acquired at B = 2.7 T in order to quench the superconductivity in the Pb-covered tip and the sample. The spectra are offset for clarity. b Amplitude over background a/b as a function of ε/Δ. a/b is extracted from the spectra as in (a). ε/Δ as extracted from the spectra at B = 0 T similar to Fig. 1c. Error bars indicate the uncertainty of the read out. For ε, the error is in the order of the symbol size
