Abstract:
In some examples, a device includes a dielectric material, a ferromagnetic material, and a topological material positioned between the dielectric material and the ferromagnetic material. The device is configured to trap electric charge inside the dielectric material or at an interface of the dielectric material and the topological material. The device is configured to switch a magnetization state of the ferromagnetic material based on a current through the topological material or based on a voltage in the topological material.
