Tailoring the electronic and magnetic properties of the layered antiferromagnet CrCl₂ — •Diana Vaclavkova, Vladyslav Romankov, Niéli Daffé, and Jan Dreiser — Swiss Light Source (SLS), Paul Scherrer Institut (PSI), CH-5232 Villigen PSI, Switzerland

The electronic and magnetic properties of two-dimensional van der Waals (vdW) materials differ greatly when comparing mono- and few-layered flakes to their bulk counterparts. In the case of atomically thin single layers the substrate has a profound influence on their properties. CrCl₂, belonging to the family of vdW materials, is expected to show a geometrical frustration in the monolayer limit given antiferromagnetic interactions are present [1]. Our preliminary studies involve X-ray magnetic circular dichroism measurements of mono- and few-layered CrCl₂ deposited on different materials. Based on the initial interpretation of the experimental data, methods for tailoring the magnetic properties by careful choice of the substrate material will be discussed.
