Spin characteristics of electrons in graphene studied

Researchers from Georgia State University (GSU) and the Georgia Institute of Technology (Georgia Tech) developed a new technique to study the spin characteristics of electrons in graphene, which could move us closed to graphene-based Spintronics devices.

The research team detected spin-resonance using electrical resistance, by illuminating the device by microwaves (which causes the spin-splitting energy to equalize). The device’s resistance is altered when the microwave energy is absorbed by the device. This effect is small and difficult to measure normally, but by using Graphene, enabled them to actually witness this effect.
