Effect of multi-layering and crystal orientation on spin-orbit torque efficiency in Ni/Pt layer stacking

A. Sud, Y. -C. Lau, J. Brierley +2

We study spin-orbit torques (SOTs) in Ni/Pt bi-layers and multi-layers by ferromagnetic resonance (FMR) and harmonic-Hall measurements. The effect of multi-layering and crystal ori…
