Spin-Hall effect due to the bulk states of topological insulators: Extrinsic contribution to the conserved spin current
James H. Cullen, Dimitrie Culcer
The substantial amount of recent research into spin torques has been accompanied by a revival of interest in the spin-Hall effect. This effect contributes to the spin torque in man…
Topological nature of the proper spin current and the spin-Hall torque
Hong Liu, James H. Cullen, Dimitrie Culcer
Spin currents are key to spin torque devices, but determining the proper spin current is non-trivial. Here we derive a general quantum-mechanical formula for the intrinsic proper s…
Spin-orbit torques due to topological insulator surface states: an in-plane magnetization as a probe of extrinsic spin-orbit scattering
Mohsen Farokhnezhad, James H. Cullen, Dimitrie Culcer
Topological insulator (TI) surface states exert strong spin-orbit torques. When the magnetization is in the plane its interaction with the TI conduction electrons is non-trivial, a…
