Experimental prototype of a spin-wave majority gate

Featuring low heat dissipation, devices based on spin-wave logic gates promise to comply with increasing future requirements in information processing. In this work, we present the experimental realization of a majority gate based on the interference of spin waves in an Yttrium-Iron-Garnet-based waveguiding structure. This logic device features a three-input combiner with the logic information encoded in a phase of 0 or π of the input spin waves. We show that the phase of the output signal represents the majority of the three phase states of the spin waves in the three inputs.
