The emerging field of 'topological spintronics' is rooted in the recent realization that narrow band gap semiconductors such as the Bi- and Sb-chalcogenides support two dimensional (2D) helical Dirac fermion surface states characterized by a spin-texture in momentum space [1,2]. Spin- and angle-resolved photoemission spectroscopy  has revealed the linear dispersion and the 'spin-momentum locking' of the 2D surface states in these three dimensional (3D) 'topological insulators.' Electrical transport measurements have also shown evidence for spin-momentum locking [4-7], although in devices that contain both bulk and surface conduction. The spin-momentum locking of 2D helical Dirac states lends itself naturally to spintronic device applications and is in particular expected to result in efficient spin-to-charge conversion. In this talk, we present an overview of recent experiments that explore the emergence of 'topological spintronics,' a potential device technology that exploits the helical Dirac spin texture for manipulating the magnetization of a vicinal ferromagnet.
