Anisotropic Magnetoresistance in Topological Insulators

We study new types of anisotropic magnetoresistance (AMR) effects. In particular, we have been interested in using the magnetic proximity effect to induce ferromagnetism into a topological insulator (TI) with a ferromagnetic insulator. If magnetism is successfully introduced into the TI, AMR effects should be present.

Additionally, we utilize existing AMR effects in material systems to study magnetization dynamics. In magnetic heterostructures, we use AMR to detect magnetization dynamics by using DC currents to induce auto-oscillatory behavior in a magnetic layer from a non-magnetic layer.
