Electrical control of magnetization is of crucial importance for integrated spintronics devices. Spinorbit torques (SOT) in heavy-metal/ferromagnetic heterostructures have emerged as promising tool to achieve efficiently current-induced magnetization reversal. However, the microscopic origin of the SOT is being debated,with the spin Hall effect (SHE) due to nonlocal spin currents and the spin Rashba-Edelstein effect (SREE) due to local spin polarization at the interface being the primary… 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
Spin Hall Effect
It is proposed that when a charge current circulates in a paramagnetic metal a transverse spin imbalance will be generated, giving rise to a ``spin Hall voltage.'' Similarly, it is proposed that whenExpand

Orbital Rashba effect in a surface-oxidized Cu film
Recent experimental observation of unexpectedly large current-induced spin-orbit torque in surface oxidized Cu on top of a ferromagnet suggested a possible role of the orbital Rashba effect (ORE).Expand
Absence of spin current generation in Ti/FeCoB bilayers with strong interfacial spin-orbit coupling
We report a quantitative investigation of the absence/presence of spin current generation by interfacial spin-orbit coupling (ISOC) at a normal metal/ferromagnet (NM/FM) interface. Utilizing theExpand
Current-induced torque originating from orbital current
The electrical manipulation of magnetization by current-induced spin torques has given access to realize a plethora of ultralow power and fast spintronic devices such as non-volatile magneticExpand
Detection of spin-orbit torque with spin rotation symmetry
It has been recently demonstrated that spin–orbit coupling in ferromagnetic metals can generate spin current with symmetries different from the conventional spin Hall effect in nonmagnetic metals. ...
Detection of the Orbital Hall Effect by the Orbital-Spin Conversion.
The intrinsic orbital Hall effect (OHE), the orbital counterpart of the spin Hall effect, was predicted and studied theoretically for more than one decade, yet to be observed in experiments. Here weExpand
Disentanglement of Spin-Orbit Torques in Pt / Co Bilayers with the Presence of Spin Hall Effect and Rashba-Edelstein Effect
We demonstrate a quantitative disentanglement of current-induced spin-orbit torques (SOTs) in $\mathrm{Pt}$/$\mathrm{Co}$ bilayers, where both the spin Hall effect (SHE) and the Rashba-EdelsteinExpand
