About

We study emergent magnetism and spin transport in single organic molecules. Spin-dependent hybridization with ferromagnetic substrates and chirality-induced spin selectivity open new avenues to tunable quantum properties in intrinsically non-magnetic molecules, which advance the control of nanoscale spin currents, e.g. for quantum information technology and spin chemistry.

Chirality Meets Quantum Mechanics

To advance the microscopic understanding of chirality-induced spin selectivity (CISS), we investigate enantioselective adsorption and enantioselective electron transport on single chiral molecules adsorbed on ferromagnetic surfaces using spin-polarized scanning tunneling microscopy and spectroscopy (SP-STM/STS).

Hybrid Molecular Magnets

Hybrid molecular magnets (HMM) are formed by spin-dependent hybridization upon adsorption of non-magnetic aromatic molecules on ferromagnetic surfaces. We investigate the formation of HMM and their magnetic and electronic properties at the single-molecule level in view of applications in spintronic memory and logic devices.
