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.
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

The effective field torque of an yttrium-iron-garnet (YIG) film on the spin accumulation in an attached platinum (Pt) film is measured by the spin-Hall magnetoresistance (SMR). As a result, theExpand

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.
