Title:
SPIN INJECTION ELECTRODE PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2012/070217
Kind Code:
A1
Abstract:
This production method includes: a first step for preparing multilayer graphene and ferromagnetic, Fe3O4-containing iron oxide contacting the graphene; and a second step for applying voltage or a current between the graphene and the iron oxide with the graphene side as the positive, oxidizing part of the graphene or part of the graphene and the Fe3O4, and forming a barrier layer configured from the oxidized graphene or the oxidized graphene and the Fe2O3 between the graphene and iron oxide, thereby providing graphene, iron oxide, and a barrier layer disposed at the interface of the graphene and the iron oxide, and forming a spin injection electrode capable of injecting spin from the iron oxide into the graphene via the barrier layer. This production method makes it possible to obtain a spin injection electrode capable of achieving highly efficient spin injection for graphene.
