Ferromagnetic graphenes and spin valve devices including the same

摘要

A ferromagnetic graphene includes at least one antidot such that the ferromagnetic graphene has ferromagnetic characteristics. A spin valve device includes a ferromagnetic graphene. The ferromagnetic graphene includes a first region, a second region, and a third region. At least one antidot is formed in each of the first region and the third region. The first region and the third region are ferromagnetic regions, whereas the second region is a non-ferromagnetic region.
