Abstract
We propose a method of realizing an effective electron spin beam splitter in graphene through the Goos-Hänchen effect. The device consists of a layer of monolayer graphene on which two ferromagnetic stripes are deposited with parallel or antiparallel magnetization configuration. It is shown that the transmitted spin-up and spin-down electron beams are found at different longitudinal positions and their spatial separation can be enhanced by the number of transmission resonances formed between the two ferromagnetic stripes. The spatial separation between the spin-up and spin-down electron beams can reach values up to hundreds of wavelengths, which can be observed experimentally.
