Abstract

A spin-based logic device is proposed. It is comprised of a common free ferromagnetic layer and four discrete ferromagnetic nanopillars, each containing an independent fixed layer. It has the functionality of a majority gate and is switched via motion of domain walls by spin transfer torque. Validity of its logic operation and a quantitative performance prediction are demonstrated by micromagnetic simulation. It is entirely compatible with complimentary metal-oxide-semiconductor technology.
