Fig. 4. Calculation of hybridized Shiba states in an AFM-coupled Mn dimer.
LDOS inside the superconducting gap calculated between the two atoms of the out-of-plane AFM-aligned dimer (blue), for a single adatom (black) and on the bare superconductor (gray), a without and f with taking SOC into account. The spectrum is convoluted with the superconducting DOS of the tip. Shiba states are labeled and marked by arrows. Two-dimensional maps of the LDOS at the indicated bias voltages show the spatial profiles of the states without (b–e) and with (g–n) SOC. Red circles denote the positions of the adatoms in the dimer. The white scale bar has a length of 500 pm. The crystallographic axes are the same as in Fig. 3b. Magnetic and non-magnetic scattering parameters with and without SOC are given in Supplementary Tables 1 and 2, respectively.
