Magnetism at the interface of the MoSe₂/V₂O₅ heterostructure

Magnetism in doped transition metal dichalcogenide monolayers and van der Waals interfaced materials have motivated the search for sustainable magnetic states at the nanoscale with the prospect of building devices based on these heterostructures suitable for spintronics applications. In this study, we report the existence of magnetism in a heterostructure made up of an

MoSe₂ transition metal dichalcogenide monolayer and a V₂O₅ substrate. Using density functional theory simulations, we find that ferromagnetic ordering can be found in the MoSe₂/V₂O₅ heterostructure even though the individual components are nonmagnetic. By examining the electronic structure and magnetic properties of this system we find how the occurring ferromagnetism evolves if the transition metal dichalcogenide or the V₂O₅ substrate can host point defects. Our study suggests that the balance between charge transfer and spin reorganization can lead to interface magnetism in novel hybrid materials.
