Unprecedented Electronic Phenomena Discovered in Graphene

Researchers from MIT have discovered a unique configuration of five layers of graphene that exhibits a rare magnetic property called a "multiferroic" state, as well as a never-before-seen electronic behavior known as ferro-valleytricity. This arrangement of graphene layers allows for interactions between electrons, resulting in quantum effects and the emergence of preferred, ferroic orders. The material's multiferroic properties could have applications in energy-efficient magnetic storage devices capable of storing double the amount of information compared to conventional devices.
