Abstract :
We proved for the first time the feasibility of the DW motion control by electric field using the exchange interaction between Gr electrons and the FMI layer. A device prototype is designed and modeled. It is shown an effective magnetic field at 10-100 Oe is generated upon the DW, which leads to a velocity around 30 m/s. 0.5-1 GHz operating frequency is expected in this condition as a bi-state memory. No active current is present and the equivalent circuit model is a set of capacitors. Therefore, low energy consumption is achieved, about 10-16 J/switch.
