N2 - This paper presents a computational study of logic devices built from single-domain Co/Pt nanomagnets, where magnetic properties of the dots are engineered by an inhomogenous focused ion beam (FIB) irradiation. We develop a micromagnetic model for such Co/Pt dots and show that their reversal behavior and coupling to neighboring dots can be precisely engineered by the dose and spatial distribution of the irradiation. We demonstrate that magnetic logic circuits and nonvolatile memory devices with attractive performance figures can be built from asymmetrically irradiated dots.
