Discovery of a monolayer van der Waals magnet using molecular beam epitaxy

Since the discovery of monolayer graphene, a variety of two-dimensional (2D) van der Waals materials have been heavily explored for their unique properties. In 2017, the first discovery of a monolayer van der Waals magnet was reported but had ferromagnetic ordering at low temperatures (less than 60 K). In a recent publication in Nano Letters, researchers from The Ohio State University have synthesized monolayer MnSe2 which is a van der Waals magnet that has ferromagnetic ordering persisting up to room temperature. This discovery is promising for future applications including non-volatile information storage and logic devices. Learn more about Dante O'Hara and his research here.
