Controlling Spin-Waves by Inhomogeneous Spin-Transfer Torques
Lorenzo Gnoatto, Jean F. O. da Silva, Artim L. Bassant +4
We investigate the interplay between spin currents and spin waves in nanofabricated Permalloy waveguides with geometrical constrictions. Using propagating spin-wave spectroscopy, m…

Current-Induced Modulation of Spin-Wave Propagation in a Y-Junction via Transverse Spin-Transfer Torque
Lorenzo Gnoatto, Rai M. Menezes, Artim L. Bassant +3
We report the transverse control of spin-wave propagation in the configuration where the spin-wave wavevector k is perpendicular to the charge-current density J. Building on theore…
