Abstract

The role of topological insulator (TI) bulk states in the the enormous spin torques recorded at TI/ferromagnet (FM) interfaces is poorly understood. Here we study spin torques due to TI bulk states focusing on magnetized TIs. We find that there is a novel spin transfer torque on an inhomogeneous magnetization, it is small in our idealized
