Abstract

The Fe₃O₄(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 lay- ers on graphene/Ni(111) were prepared via successive oxida- tion of a thin iron layer predeposited on graphene/Ni(111) and the formed system was investigated by means of low- energy electron diffraction and photoelectron spectroscopy. The electronic structure and structural quality of the graphene film sandwiched between two ferromagnetic layers remain unchanged upon magnetite formation as confirmed by ex- perimental data.
