石墨烯-石墨的单原子层-是最近发现的碳的二维（2-D）形式，其在室温下表现出高晶体质量和弹道电子传输。软磁NiFe电极已被用于将极化自旋注入石墨烯中，并且当电极从平行状态切换到反平行状态时，已观察到电阻的10%变化。这与场效应电极可以调节这些石墨烯膜的导电性的事实相结合，使它们成为自旋电子器件的潜在候选者。
Graphene-a single atomic layer of graphite-is a recently found two-dimensional (2-D) form of carbon, which exhibits high crystal quality and ballistic electron transport at room temperature. Soft magnetic NiFe electrodes have been used to inject polarized spins into graphene, and a 10% change in resistance has been observed as the electrodes switch from the parallel to the antiparallel state. This coupled with the fact that a field-effect electrode can modulate the conductivity of these graphene films makes them exciting potential candidates for spin electronic devices.
