Spin waves for interconnect applications

In this paper, we investigate spin wave propagation in scaled magnetic waveguides for magnetic interconnect applications. We show experimentally that spin waves can travel over several micrometers distance which potentially covers more than 80% of interconnects needed in a low-density parity-check design implemented in the CMOS 7 nm node. Furthermore, we demonstrate the existence of a unidirectional spin wave mode that can propagate in bent waveguides, enabling signal routing without changing the metal layer.
