Experimental Realization of a Nanomagnet Full Adder Using Slanted-Edge Magnets

Abstract

We present the experimental realization of a full adder circuit using Nanomagnet Logic (NML). The circuit relies heavily on the properties of asymmetric slant magnets that allow robust operation and reduced footprint. We demonstrate stand-alone NML majority gates and wires, and interconnect these components into an NML full adder that functions properly for all 8 input combinations. To our knowledge, this is the first working implementation of an NML full adder from in-plane magnetized nanomagnets, and one of the very few existing non-electrical, room temperature nanoscale computing units.
