Spin waves, which can propagate free of Joule heating, may act as the information carrier in future spintronic technology. In antiferromagnets (AFMs), spin waves are fast and insensitive to external magnetic fields, but current-induced excitation and control of the propagation is difficult to achieve. Liu et al. now explore spin waves in an artificial AFM structure, which consists of periodic 100-nm-wide stripe domains with alternating upward and downward magnetization. They excite high-frequency spin waves, which propagate along the strips. Furthermore, they can reorient the domain pattern by current pulses and, thereby, control the propagation direction of the spin waves. The cover art shows spin waves propagating within domains of opposite spin polarization as indicated by the yellow and purple arrows.
