Antiferromagnetic Domain Wall Motion Driven by Spin-Orbit Torques.
We theoretically investigate the dynamics of antiferromagnetic domain walls driven by spin-orbit torques in antiferromagnet-heavy-metal bilayers. We show that spin-orbit torques drive antiferromagnetic domain walls much faster than ferromagnetic domain walls. As the domain wall velocity approaches the maximum spin-wave group velocity, the domain wall undergoes Lorentz contraction and emits spin...

متن کاملCurrent-induced domain wall motion with adiabatic and nonadiabatic spin torques in magnetic nanowires
We investigate current-driven domain wall (DW) propagation in magnetic nanowires in the framework of the modified Landau-Lifshitz-Gilbert equation with both adiabatic and nonadiabatic spin torque (AST and NAST) terms. By employing a simple analytical model, we can demonstrate the essential physics that any small current density can drive the DW motion along a uniaxial anisotropy nanowire even i...
متن کاملDeterministic Domain Wall Motion Orthogonal To Current Flow Due To Spin Orbit Torque
Spin-polarized electrons can move a ferromagnetic domain wall through the transfer of spin angular momentum when current flows in a magnetic nanowire. Such current induced control of a domain wall is of significant interest due to its potential application for low power ultra high-density data storage. In previous reports, it has been observed that the motion of the domain wall always happens p...
متن کاملDomain wall motion in nanowires
We investigated the motion of domain walls in ferromagnetic cylindrical nanowires by solving the Landau Lifshitz Gilbert equation numerically for a classical spin model in which energy contributions from exchange, crystalline anisotropy, dipole dipole interactions, and a driving magnetic field are considered. Depending on the diameter, either transverse domain walls or vortex walls are found. A...
