New aspects of magneto-chiral surface physics: Inducing magnetization in antiferromagnetic monolayers by adsorption of chiral molecules

Intriguing investigations spanning the last two decades have showcased the capacity of
chiral molecular assemblies to serve as electron spin filters - an occurrence recognized as the chirality-induced spin selectivity (CISS) effect. In addition, the preferred adsorption of chiral molecules on ferromagnetic domains with opposite magnetization hints towards spin and handedness selective adsorption energies/processes. This implies that the adsorption of an enantiopure monolayer of a chiral molecule can lead to the stabilization/destabilization of spin up/down moments in an antiferromagnetic (AFM) layer. Hence, it should be possible to induce a net-magnetic moment by adsorption of a monolayer of chiral moments. Here, we propose to study antiferromagnetic thin films with adsorbed chiral molecules by XAS/XMCD/XLD (XNLD;
XMLD).
