摘要

We present a methodology design of spin-wave-based multi-input logic gates by applying a local spin-polarized current on a single ferromagnetic stripe. Micromagnetic simulation shows that the phase of propagating spin waves in a single ferromagnetic nanostripe can be shifted by /5 without decreasing its amplitude when they pass through an area with nonlinear internal field. The methodology adopting spin-transfer torque effects to fulfill spin-wave-based multi-input logic gates is demonstrated in a single ferromagnetic waveguide. The structure of designed logic gates can be simplified significantly compared with the prototype Mach–Zehnder-type interferometer type gates.
