Magnetic superlattices from elastic Landau levels in graphene/NbSe2 heterostructures
ABSTRACT
We show that a hybrid graphene/NbSe2 multilayers yields the formation of a periodically modulated ferrimagnetic groundstate, emerging from an elastic pseudo Landau level, controllable by the application of external electric fields. Our results build on top of recent experimental findings reporting that, when placed on top of a NbSe2 substrate, graphene sheets relax forming a periodic, long-range buckling pattern caused by the lattice mismatch.

Hi, I am a phd student at Leiden University, I work both with NbSe2 and graphene. I am wondering what happens to the transport properties in this configuration? With the NbSe2 being a superconducting materials, do you expect a normal proximity effect in graphene?
Hi Xing!
We haven’t looked into transport properties yet, but we working on it and I’ll be happy to discuss in case you are interested. Please email me 🙂
That said, if you watched Eva Andrei’s lecture, you probably heard that they saw no superconductivity in their samples.
