Interfacial and bulk spin Hall contributions to field-like spin-orbit torque generated by Iridium

Sutapa Dutta, Arnab Bose, A. A. Tulapurkar +2

We present measurements of spin orbit torques generated by Ir as a function of film thickness in sputtered Ir/CoFeB and Ir/Co samples. We find that Ir provides a damping-like compo…
