Abstract

It is shown experimentally that the interaction of chiral molecules with a perpendicularly magnetized substrate is enantiospecific. Thus, one enantiomer adsorbs preferentially when the magnetic dipole is pointing up, whereas the other adsorbs faster for the opposite magnetization alignment. The interaction is not controlled by the magnetic field but by the respective electron spin orientations. Magnetization reorientation of magnetic layer can be realized solely by adsorption of chiral molecules on its surface without presence of magnetic or electric fields.
