Graphene shows record-breaking magnetic properties.

Next, the researchers applied different magnetic fields to the graphene to measure how its magnetoresistance changed. This is partly down to graphene's electrons and holes being highly mobile and therefore sensitive to tiny changes in an external magnetic field, the researchers write in their paper. Its unparalleled ability to increase or decrease its electrical resistance in response to a magnetic field could one day have applications for how we store data. [Extracted from the article]
