Graphene Becomes Magnetic and Electric at Same Time

Graphene Becomes Magnetic and Electric at Same Time

Combining the electric with the magnetic in one material has become a hot research pursuit lately. First researchers exploited the natural properties of bismuth ferrite . Then researchers engineered both electric and magnetic polarization in perovskite —a material that does not have that property naturally. Now researchers at the University of California Riverside have brought this combination of the electric and the magnetic to the wonder material, graphene . Of course, it is possible to induce magnetism in graphene by doping the material with magnetic impurities. Unfortunately, that process comes at the high cost of eliminating all the attractive electrical properties of graphene, such as its high conductivity. The UC Riverside researchers found a way to make graphene magnetic without sacrificing its attractive electrical properties. “This is the first time that graphene...
