Suppression of the fieldlike spin-orbit torque efficiency due to the magnetic proximity effect in ferromagnet/platinum bilayers

T. A. Peterson, A. P. McFadden, C. J. Palmstrøm +1

Current-induced spin-orbit torques in Co${}_2$FeAl/Pt ultrathin bilayers are studied using a magnetoresistive harmonic response technique, which distinguishes the dampinglike and fie…
