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).
