Abstract
Abstract For the first time, we explore all possible two-input logical operations (OR, AND, NOT, NOR, NAND, XOR, and XNOR) using a single-stranded antiferromagnetic (AFM) helix system. The AFM helix produces a large amount of spin current in the presence of a transverse electric field. The spin current, considered as the output, can be tuned by the strength and direction of the electric field that are taken as the inputs of the logic gates. All the results are spin-based, which reduces the loss due to heating energy, and since the operations are reprogrammable, one can have all the gates in a single system simply by rearranging the setup. Based on the growth of experimental realization of AFM helical systems we believe that our results can be verified and may lead to a new direction in the branch of AFM spintronics.
