Abstract

We study the exchange coupling between magnetization in FM and the spin-polarized current in TI and discover rich nonlinear dynamical behavior. 1. We find chaotic regime, phase synchronization regime and multistability regime. 2. The multistability regime provides an efficient way to control the state of the magnetization in the FM and the phase of the anomalous Hall current in the TI. 3. The system can dynamically induce an anomalous Hall conductance which possesses an unconventional dependence on the channel conductance.
