The spin-orbit torque was generated by a transverse microwave current across the magnetic waveguide. The detected spin wave signals for an in-plane magnetization across the waveguide (Damon-Eshbach configuration) exhibited the expected phase rotation and amplitude decay upon propagation when the current spreading was taken into account. Wavevectors up to about 6 rad/$\\mu$m could be excited by the spin-orbit torque antennas despite the curre","authors_text":"Christoph Adelmann, Florin Ciubotaru, Giacomo Talmelli, Iuliana P.
