Abstract Magnetic domain-wall devices such as racetrack memory and domain-wall shift registers facilitate massive data storage as hard disk drives with low power portability as flash memory devices. The key issue to be addressed is how perfectly the

The electric-current-induced spin torque on local magnetization allows the electric control of magnetization, leading to numerous key concepts of spintronic devices. Utilizing the steady-state spin precession under spin-polarized current, a nanoscale

Here, we demonstrate an optical spin–orbit torque (SOT) measurement scheme that is free from artifacts such as the optic planar Hall effect (PHE) and the optic anomalous Nernst effect (ANE). Such PHE and ANE signals complicate the SOT analysis in t

Here, we present an analytic formula for the domain-wall depinning current from artificial triangular notches driven by the spin–orbit torque combined with the Dzyaloshinskii–Moriya interaction. Interestingly, in contrast to the magnetic-field-dr
