Summary:Spin waves (SWs) are considered the most promising alternative for post-CMOS technology as they offer Joule heating-less data transmission capability. SWs-based logic devices can be implemented by harnessing the linear wave interference property of SWs. On-demand reconfiguration of logic gates might reduce the chip footprint significantly. However, the energy-efficient control of SWs for implementing such reconfigurability is still a challenge. Here, we have proposed and experimentally demonstrated an SWs interference-based XOR logic gate that can be reconfigured to an XNOR logic gate by changing the thermal landscape by 3 K in a microstructured magnonic cross-bar. We asserted that the mechanism behind the reconfigurability is related to the conversion of SW wavelength and frequency due to the change of the thermal landscape by the Peltier device. A more efficient frequency controlling technique is expected to enhance the energy efficiency of the propose device.
