Fig. 3: YSR state of Tb₂Pc₃.

a dI/dV mapping of the Tb₂Pc₃ in Fig. 2a at 0.3 mV, showing the intensity distribution of the YSR state. ) Selective spectra (V = 10 mV and I = 100 pA) taken at the indicated positions in (a). The gray lines depict the energies of the superconducting coherence peaks of Pb. c Variation of YSR states taken at the same location of a Tb₂Pc₃ with decreasing tip height δZ. The δZ = 0 pm value is set at V = 10 mV and I = 50 pA. d Statistics showing the relation between E_b and T_K relative to the Pb superconducting gap Δ. Black (red) solid dots are experimental outer (inner) YSR state. Pink (blue) hollow dots are theoretically calculated outer (inner) YSR states.
