Graphene is a special material. Among its many talents, it can act as a superconductor, generate a super-rare form of magnetism, and unlock entirely new quantum states.

Now graphene has another amazing credit: it can record levels of magnetoresistance without a need to push the temperature down towards absolute zero.

High magnetoresistance – a material’s ability to change its electrical resistance in response to a magnetic field – is relatively rare, yet materials that can shift their properties in this fashion are useful in computers, cars, and medical equipment.
