Abstract

A voltage-controlled magnetic based device is described that includes a magnetic insulator; a topological insulator adjacent the magnetic insulator; and magnetic dopants within the topological insulator. The magnetic dopants are located within an edge region of the topological insulator to inhibit charge current flow in the topological insulator during a switching operation using an applied electric field generating by applying a switching voltage across two electrodes at opposite sides of the topological insulator. Power dissipation due to carrier-based currents can be avoided or at least minimized by the magnetic dopants at the edges of the topological insulator.
