Reconfigurable Spin Orbit Logic Device Using Asymmetric Dzyaloshinskii-Moriya Interaction

A spin-orbit torque-based logic device that combines the Dzyaloshinskii-Moriya interaction and asymmetric shape anisotropy is proposed in this paper. Through magnetization switching of the magnetic tunnel junction (MTJ), four distinct input cases are determined to perform all of the 16 basic Boolean functions by a single magnetic tunnel junction (MTJ). With various combinations of the tilted angle of the MTJ and the value of current density, a single MTJ can serve as a reconfigurable logic gate.
