Recently, researchers in the UK, led by Nobel laureate Andre Geim have found that graphene displays an anomalous giant magnetoresistance (GMR) at room temperature.
About Magnetoresistance:
What is it? It is the result of the electrical resistance of a conductor affected by magnetic fields in adjacent materials.
Applications: It is used in hard disk drives and magneto resistive RAM in computers, biosensors, automotive sensors, microelectromechanical systems, and medical imagers etc.
Key facts about Graphene
It is composed of monolayer of closely packed carbon atoms that form a hexagonal honeycomb lattice.
It is the building-block of Graphite.
It is the thinnest,most electrically and thermally conductive material in the world.
It is also tremendously strong—about 200 times stronger than steel and flexible, as well as transparent.
It is also known as a wonder material due to its vast potential in the energy and medical world.
