Interface Effects on Electronic and Magnetic Properties of 2D van der Waals Magnets on Metal Substrates

The PhD topic aims to study the impact of metal interfaces on electronic and magnetic properties of magnetic two-dimensional van-der-Waals materials. The bonding to the metal is expected to affect these materials in the single layer limit via charge transfer effects, band structure distortions, magnetic couplings and magnetic anisotropy energies. The interface-induced inversion symmetry breaking is predicted to cause non-collinear spin textures like skyrmions. A particular interest lies in moiré effects, arising on (111) metal facets due to the mismatch of the atomic lattices at the interface and their relative azimuthal orientation. The PhD candidate would combine spatially- and angle-resolved photoemission spektroscopy and scanning tunneling spectroscopy to study these effects.
