  Spin waves are propagating disturbances in magnetically ordered materials,
analogous to lattice waves in solid systems and are often described from a
quasiparticle point of view as magnons. The attractive advantages of
Joule-heat-free transmission of information, utilization of the phase of the
wave as an additional degree of freedom and lower footprint area compared to
conventional charge-based devices have made spin waves or magnon spintronics a
promising candidate for beyond-CMOS wave-based computation. However, any
practical realization of an all-magnon based computing system must undergo the
essential steps of a careful selection of materials and demonstrate robustness
with respect to thermal noise or variability. Here, we aim at identifying
suitable materials and theoretically demonstrate the possibility of achieving
error-free clocked non-volatile spin wave logic device, even in the presence of
thermal noise and clock jitter or clock skew.
