• magnetoelectric effect

We propose a two-input configuration of a magnetic tunnel junction (MTJ) for use as a programmable logic element. The MTJ intrinsically performs four logic functions-NAND, NOR, IMP, and NIMP-based on two physically independent inputs whose values are determined by magnetic field and the voltage bias. By applying the surface magnetoelectric effect, four distinct input states are determined to perform these logic operations through switching of the MTJ. With predetermined logic inputs, a single MTJ can serve as a programmable logic gate that represents all fundamental logic functions.
