Spin-wave logic devices offer large advantages compared to modern CMOS-based elements. An example for such a logic element is the majority gate. In this contribution, we present the investigation of a macroscopic spin-wave majority gate device made from a YIG film. We examine the spin-wave propagation by means of microwave techniques. The operation of the device as a majority gate was proven - the output phase of the signal was defined by the majority of the input phases. Additional time-resolved measurements have shown that the device can switch logic output within approximately 11 ns. In order to scale down spin-wave majority devices we fabricate microstructured combiner structures made from a 100 nm thick YIG film and examine the spin-wave transmission and reflection of different combiner structures by using Brillouin light scattering microscopy. This research has been supported by: EU-FET Grant InSpin 612759, ERC Starting Grant 678309 MagnonCircuit, and DFG (DU 1427/2-1).
