Innovative orderly programmable in‐plane majority gates using trapezoid shape nanomagnet logic devices

Abstract

Programmable circuit components are indispensable for nanomagnet logic (NML, also called magnetic quantum‐dot cellular automata) devices. Two alternative programmable majority gates (PMGs) (PMG1 and PMG2) for in‐plane NML are proposed. The presented designs both utilise trapezoid shape nanomagnets (nanomagnet with a slanted edge) to form the structures. With only a uniform layout and a homogeneous clocking field, the proposed structures can orderly reconfigure eight input combinations of the majority gates, and they also demonstrate superior performance over the regular shape nanomagnet‐based PMG. The innovative design could find technological application in the field of majority gate‐based programmable magnetic circuits (e.g. programmable nanomagnetic Full Adder).
