摘要: Abstract Graphene is a 2D material that displays excellent electronic transport properties with prospective applications in many fields. Inducing and controlling magnetism the graphene layer, for instance by proximity of magnetic materials, may enable its utilization spintronic devices. This paper presents fabrication detailed characterization single-layer formed on surface epitaxial FeRh thin films. The state can be controlled temperature, field or strain due to interconnected order parameters. Characterization layers X-ray Photoemission Absorption Spectroscopy, Low-Energy Ion Scattering, Scanning Tunneling Microscopy, Electron Microscopy shows single-layer, polycrystalline covers more than 97% substrate. several preferential orientations FeRh(0 0 1) unit vectors rotated 30°, 15°, 11°, 19° respect substrate vectors. In addition, layer capable protect films from oxidation when exposed air months. Therefore, it also used as protective during elements an atomically spacer, which enables incorporation switchable within stacks materials advanced
