TORQUETIME-resolved measurementsANTIFERROMAGNETIC materialsDamping effects form the core of many emerging concepts for high-speed spintronic applications. Important characteristics such as device switching times and magnetic domain-wall velocities depend critically on the damping rate. While the implications of...
Damping-like torque (DLT) arising from the spin Hall effect (SHE) in heavy metals and their alloys has been widely explored for applications in spin–orbit torque MRAM, auto-oscillations, spin waves, and domain wall motion. In conventional materials, the DLT efficiency is limited by intrinsic ...
Using the harmonic measurements, we have characterized the effective fields corresponding to the damping like torque and the field like torque, but we have found the dominancy of damping like torque in the Pt/Co/W films. It is much different from the results in the Pt/Co/AlOx films, in ...
Besides that, the CuOx thickness dependence of the damping parameter further proves the observation of antidamping-like torque. This result contributes to enriching the orbital-related theory of the generation mechanism of the orbital torque.Zeyang Gong...
Damping-like torqueSpin-torque ferromagnetic resonancePlanar Hall effectA damping-like spin-orbit torque (SOT) is a prerequisite for ultralow-power spin logic devices. Here, we report on the damping-like SOT in just one monolayer of the conducting transition-metal dichalcogenide (TMD) TaS2 ...
Spin-orbit torque (SOT) magnetization switching, which is induced by a spin current generated by a charge current, is a promising phenomenon that can be used to improve the performance of magnetoresistive random access memory. In our previous study, we achieved a highly efficient full SOT ...

Despite their great promise for providing a pathway for very efficient and fast manipulation of magnetization, spin-orbit torque (SOT) operations are currently energy inefficient due to a low damping-like SOT efficiency per unit current bias, and/or the very high resistivity of the spin Hall ...
Strong damping-like spin-orbit torque ({au}DL) has great potential for enabling ultrafast energy-efficient magnetic memories, oscillators, and logic. So far, the reported {au}DL exerted on a thin-film magnet must result from an externally generated spin current or from an internal non-...
While the magnitudes of both the damping-like and\nfield-like inverse spin-orbit torque are of comparable scale to prior reported\nvalues for similar material systems, we observed a significant dependence of\nthe damping-like magnitude on the order of deposition. This suggests interface\nquality ...
