Spin-Wave Emission by Spin-Orbit-Torque Antennas KU Leuven
© 2018 American Physical Society. We study the generation of propagating spin waves in Ta/(Co,Fe)B bilayer waveguides by spin-orbit-torque antennas and compare them with spin waves generated by conventional inductive antennas. The spin-orbit torque is generated by a transverse microwave current across the waveguide. The detected spin-wave signals for a transverse in-plane magnetization (Damon-Eshbach configuration) exhibit the expected phase ...
