We report on the switching of the in-plane magnetization of thin yttrium iron garnet (YIG)/Pt bilayers induced by an electrical current. The switching is either field-induced and assisted by a dc current, or current-induced and assisted by a static magnetic field. The reversal of magnetization occurs at a current density as low as 105 A/cm2 and magnetic fields of ∼40 μT, two orders of magnitude smaller than in ferromagnetic metals, and consistent with the weak uniaxial anisotropy of the YIG… Expand

Current-driven spin torque induced by the Rashba effect in a ferromagnetic metal layer.
TLDR
It is demonstrated that strong magnetic fields can be induced in ferromagnetic metal films lacking structure inversion symmetry through the Rashba effect and this process makes it a realistic candidate for room-temperature spintronic applications. Expand

TLDR
This work reports on the three-dimensional vector measurement of SOTs in AlOx/Co/Pt and MgO/CoFeB/Ta trilayers using harmonic analysis of the anomalous and planar Hall effects and demonstrates that heavy metal/ferromagnetic layers allow for two different Sots having odd and even behaviour with respect to magnetization reversal.
