Researchers manage to detect the electronic spin state of graphene contacted to a magnetic metal
Graphene is a promising Spintronics material, and a lot of research is dedicated to this new material. Detecting the electronic spin state of the material is not easy. Now researcher from Japan's Advanced Science Research Center, the Atomic Energy Agency and the National Institute for Materials Science developed a way to do it using a spin-polarized metastable helium beam.
The researchers also found out that in conduction electrons of graphene contacted to nickel, spin polarization occurs with the same orientation as the spin of the nickel.
