Simulation of Power Gain and Dissipation in Field-Coupled Nanomagnets

Coupled nanomagnetic dots were proposed as a promising way to realize computing devices. This paper investigates power flow phenomena in these structures. Using micromagnetic simulations we will demonstrate that the power dissipation of those devices is close to the theoretical lowest limit of any computation and that coupled nanomagnets exhibit power gain, i.e. they are active devices. These results suggest that magnetic computing could be a functionally equivalent replacement of transistor-based circuits in signal processing applications, where robust, low-power operation is crucial.     «
