Towards an ideal graphene-based spin-filter
arXiv:1102.2367 · doi:10.1002/pssr.201105197
Abstract
The FeO(111)/graphene/Ni(111) trilayer is proposed to be used as an ideal spin-filtering sandwich where the half-metallic properties of magnetite are used. Thin magnetite layers on graphene/Ni(111) were prepared via successive oxidation of thin iron layer predeposited on graphene/Ni(111) and formed system was investigated by means of low-energy electron diffraction (LEED) and photoelectron spectroscopy (PES) of core levels as well as valence band. The electronic structure and structural quality of the graphene film sandwiched between two ferromagnetic layers remains unchanged upon magnetite formation as confirmed by LEED and PES data.
