"Unveiling a Rare Electronic State: The Emergence from a Five-Layer Graphene Sandwich"

MIT physicists have discovered that when graphene is stacked in five layers in a rhombohedral pattern, it exhibits a rare "multiferroic" state called ferro-valleytricity, which combines unconventional magnetism and an exotic type of electronic behavior. This discovery could have implications for designing ultra-low-power, high-capacity data storage devices for classical and quantum computers, potentially doubling the amount of information that can be stored compared to conventional devices.
