MIT Physicists Uncover Exotic Properties and Bizarre Electronic States in Graphene

MIT physicists have discovered that when graphene is stacked in a specific five-layer pattern, it exhibits a unique "multiferroic" state, showcasing unconventional magnetism and a novel electronic behavior named "ferro-valleytricity." This finding could pave the way for the development of high-capacity, energy-efficient data storage devices. By incorporating five-layer graphene or similar multiferroic materials into memory chips, engineers could potentially double the amount of data that can be stored on a chip compared to conventional methods.
