Perfect Spin-filtering and Giant Magnetoresistance with Fe-terminated Graphene Nanoribbon
arXiv:1108.1253 · doi:10.1063/1.3626596
Abstract
Spin-dependent electronic transport properties of Fe-terminated zig-zag graphene nanoribbons (zGNR) have been studied using first-principles transport simulations. The spin configuration of proposed zGNR junction can be controlled with external magnetic field, and the tunneling junction show MR>1000 at small bias and is a perfect spin-filter by applying uniform external magnetic filed at small bias.
