Voltage Induced Switching of Nanomagnets in Topological Insulator   Magnetoelectric Devices through Ruderman-Kittel-Kasuya-Yosida Interactions
  In this letter, we demonstrate switching of nanomagnets through RKKY interactions in topological insulator-based magnetoelectric devices. The switching speed is dependent on the size of the ferromagnets.
