Abstract
We show here using atomistic simulations that NiO stripes can be used as waveguides for antiferromagnetic spin waves or domain walls. We numerically demonstrate some of their salient features including their fast velocity over 40 km/s and their interesting propagation properties enabling them to cross corners unscathed, their possible conversion into one another when changing the stripes widths, and their self-interaction. Their exotic behavior offers promising opportunities for building resilient, low-power, and ultrafast logic gates.
