Spin-wave logic devices offer large advantages compared to modern CMOS-based elements. For example spin waves promise a significant reduction of Joule heating since they avoid Ohmic losses. An example for such a logic element is the spin-wave majority gate, in which the logical output is given by the majority of the logical inputs. Besides, a spin-wave majority gate is suitable for the construction of all-magnonic circuits. In this contribution, we present the fabrication and investigation of a microstructured spin-wave majority gate device made from a 80 nm thick YIG film. We investigate the operation of the device by means of microwave techniques and performed additional measurements to examine the spin-wave propagation and transmission by using Brillouin light scattering microscopy.
