Programmable nanomagnet-logic majority gate

Abstract

Nanomagnet logic (NML) is a room temperature realization of the original quantum-dot cellular automata (QCA) concept, which is built from single-domain, e-beam patterned supermalloy nanomagnets. Many magnetic circuit elements have been experimentally realized (Fig. 1), including lines, gates, and inverters1. Calculations shows that if 1010 magnets switch 108 times/s, the magnets would dissipate ∼ 0.1 W.
