Single-Enantiomer Spin Polarizers in Superconducting Junctions
Abstract
Decorating the superconducting Pb tip of a scanning tunneling microscope with a Mn atom cluster gives rise to Yu-Shiba-Rusinov resonances that serve as spin-sensitive probes of the tunneling current in junctions of single heptahelicene molecules adsorbed on Pb(111). The signal strength of these states in spectroscopy of the differential conductance depends on the handedness of the probed molecule, the direction of current flow, and the intramolecular site. These findings support the presence of the chirality-induced spin selectivity effect and the role of a single enantiomer as a spin polarizer.
