Surface acoustic waves for magnonique devices – SACOUMAD

CMOS technology is now limited by the dissipation of the thermal energy, generated by Joule effect. To circumvent this limitation, a number of the basic building blocks of the magnonic paradigm have been experimentally demonstrated. However, they consume much energy than their CMOS counterparts. Furthermore, the demonstration of a magnonic logic gate with a fan-out ? 2 remains elusive. In our project, we propose an innovative approach for these logic gates design that solves the fan-out bottleneck and also permits energy efficient, large scale integration, of voltage controlled magnonic circuits. We will first develop a new type of spin wave (SW) generator that does not use charge current and relies on magnetostrictive resonant coupling between magnetization and surface acoustic wave. The final objective will be to demonstrate a functional majority gate with fan-out capabilities.
