Well Balanced Magnetic Gates for Inverted Logic — •Timo Pulch, Daniele Pinna, and Karin Everschor-Sitte — Johannes-Gutenberg Universität

We present an energy efficient solution for inverted logic gates by considering the self-interactions of magnets. Conventional magnetic logic gates have already been showing great results towards scaling and energy efficiency. In this work we present a series of reliable gate designs that are robust against finite temperature effects. The dipolar coupled monodomain magnet designs have been selected according to the fundamental metrics of balance and logical consistency. We argue that energy harvesting of the thermal fluctuations within this model can be used to stabilize the system in the desired logical states. In addition, we go one step further and show that carefully tuned gate structures are able to invert the logical processes of these gates. Invertible logic is a promising approach to solve NP problems.
