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

Researchers at MIT have discovered that when graphene is stacked in five layers in a rhombohedral pattern, it exhibits a rare "multiferroic" state, displaying both unconventional magnetism and an exotic electronic behavior called ferro-valleytricity. This discovery could have implications for the development of 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.
