By promising a significant reduction of Joule heating due to Ohmic losses, spin-wave logic devices offer large advantages compared to modern CMOS-based elements. Also, a majority-based logic allows for a reduction of the number of gates for implementing a given operation [1]. The magnetic insulator material yttrium iron garnet (YIG) is of particular interest for applications in this field due to its intrinsically low Gilbert damping parameter and large spin-wave propagation lengths.
In this work, we present the investigation of a macroscopic spin-wave majority gate device made from YIG films. We examine the spin-wave-propagation by means of microwave techniques.
In order to analyze the operational properties of our device, we determine the coupling among the input channels and study the dependence of the output signal amplitude and phase on the parameters of the input signals.
