Single molecule-surface hybrid systems are a promising platform for molecular spintronics due to their adjustable magnetic properties [1, 2]. In this contribution we demonstrate the creation of multiple intramolecular subunits within a single molecule-surface hybrid system employing ab initio density functional theory and spin-polarized scanning tunneling microscopy [3].
Upon deposition of a polycyclic aromatic molecule onto a ferromagnetic surface an asymmetric (chiral) adsorption geometry is obtained. This gives rise to the formation of different structural, electronic and magnetic properties of each aromatic ring hybridizing with the surface. Finally, this leads to the creation of magnetic subunits which are distinguished from one another by their exchange coupling strength [3].
