Collective skyrmion motion under the influence of an additional interfacial spin-transfer torque [PDF]
Here we study the effect of an additional interfacial spin-transfer torque, as well as the well-established spin–orbit torque and bulk spin-transfer torque, on skyrmion collections—group of skyrmions dense enough that they are not isolated from one ...

Magnetisation switching dynamics induced by combination of spin transfer torque and spin orbit torque [PDF]
We present a theoretical investigation of the magnetisation reversal process in CoFeB-based magnetic tunnel junctions (MTJs). We perform atomistic spin simulations of magnetisation dynamics induced by combination of spin orbit torque (SOT) and spin ...

Nonresonant amplification of spin waves through interface magnetoelectric effect and spin-transfer torque [PDF]
We present a new mechanism for manipulation of the spin-wave amplitude through the use of the dynamic charge-mediated magnetoelectric effect in ultrathin multilayers composed of dielectric thin-film capacitors separated by a ferromagnetic bilayer ...

Theory of current-induced angular momentum transfer dynamics in spin-orbit coupled systems
Motivated by the importance of understanding various competing mechanisms to the current-induced spin-orbit torque on magnetization in complex magnets, we develop a theory of current-induced spin-orbital coupled dynamics in magnetic heterostructures. The

Non-equilibrium spatial distribution of Rashba spin torque in ferromagnetic metal layer
We study the spatial distribution of spin torque induced by a strong Rashba spin-orbit coupling (RSOC) in a ferromagnetic (FM) metal layer, using the Keldysh non-equilibrium Green's function method.

Nanoscale interface confinement of ultrafast spin transfer torque driving non-uniform spin dynamics [PDF]
Fundamental understanding of ultrafast spin dynamics is crucial for spintronics applications. Here the authors demonstrate an ultrafast technique to explore the inhomogeneous THz spin dynamics in Fe/Au/Fe multilayers triggered by spin transfer torque.

Effect of spin relaxations on the spin mixing conductances for a bilayer structure
The spin current can result in a spin-transfer torque in the normal-metal(NM)—ferromagnetic-insulator(FMI) or normal-metal(NM)—ferromagnetic-metal(FMM) bilayer.
