Abstract

Graphene takes spin Electronic transport in single or a few layers of graphene — a form of graphite just one atom layer thick — is the subject of intense interest. Graphene may be a promising material for spintronics, where both the spin and the charge of electrons are used for novel devices. Tombros et al. take a step in this direction by studying the transport of electron spin in single layers of graphene. The experiments involve graphene sheets making contact with ferromagnetic cobalt electrodes through a thin insulating layer. In this system electron spin can be transported over lengths of 1–2 µm, and transport over longer distances should be possible with samples of improved electronic quality.
