In metallic ferromagnets, the interaction between local magnetic moments and conduction electrons renormalizes parameters of the Landau-Lifshitz-Gilbert equation such as the gyromagnetic ratio and the Gilbert damping, and makes them dependent on the magnetic configurations. Although the effects of the renormalization for nonchiral ferromagnets are usually minor and hardly detectable, we show that the renormalization does play a crucial role for chiral magnets. Here the renormalization is chiral…

Theory of chiral effects in magnetic textures with spin-orbit coupling
We present a theoretical study of two-dimensional spatially and temporally varying magnetic textures in the presence of spin-orbit coupling (SOC) of both the Rashba and Dresselhaus types. We show

Atomic antiferromagnetic domain wall propagation beyond the relativistic limit
We theoretically investigate the dynamics of atomic domain walls (DWs) in antiferromagnets driven by a spin-orbit field. For a DW with a width of a few lattice constants, we identify a Peierls-like
Comparative study of methodologies to compute the intrinsic Gilbert damping: interrelations, validity and physical consequences.
This work unambiguously demonstrates that the damping parameter obtained within the constant broadening approximation diverges for three-dimensional bulk magnets in the clean limit, while it remains finite for monolayers.
Disentangling factors governing Dzyaloshinskii domain-wall creep in Co/Ni thin films using PtxIr1−x seed layers
We characterize asymmetric growth of magnetic bubble domains in perpendicularly magnetized Co/Ni multi-layers grown on Pt$_x$Ir$_{1-x}$ seedlayers by application of perpendicular and in-plane
Rashba Effect in Functional Spintronic Devices.
Progress is mainly on progress related to the two most compelling devices that exploit the Rashba effect: spin transistors and spin-orbit torque devices.
Effect of Chiral Damping on the dynamics of chiral domain walls and skyrmions
Friction plays an essential role in most physical processes that we experience in our everyday life. Examples range from our ability to walk or swim, to setting boundaries of speed and fuel


Hydrodynamic theory of coupled current and magnetization dynamics in spin-textured ferromagnets
We develop the hydrodynamical theory of collinear spin currents coupled to magnetization dynamics in metallic ferromagnets. The collective spin density couples to the spin current through a U(1)
Chiral damping of magnetic domain walls.
It is reported that the structural inversion asymmetry (SIA) gives rise to a chiral damping mechanism, which is evidenced by measuring the field-driven domain-wall motion in perpendicularly magnetized asymmetric Pt/Co/Pt trilayers.
Current-driven dynamics of chiral ferromagnetic domain walls.
This work directly confirms the DW chirality and rigidity by examining current-driven DW dynamics with magnetic fields applied perpendicular and parallel to the spin spiral and resolves the origin of controversial experimental results.
Chiral damping, chiral gyromagnetism, and current-induced torques in textured one-dimensional Rashba ferromagnets
We investigate Gilbert damping, spectroscopic gyromagnetic ratio and current-induced torques in the one-dimensional Rashba model with an additional noncollinear magnetic exchange field. We find that
Role of nonlinear anisotropic damping in the magnetization dynamics of topological solitons
The consequences of nonlinear anisotropic damping, driven by the presence of Rashba spin-orbit coupling in thin ferromagnetic metals, are examined for the dynamics of topological magnetic solitons
Roles of nonequilibrium conduction electrons on the magnetization dynamics of ferromagnets.
This work compute the response of the conduction electron spins in a spatial and time varying magnetization M(r,t) in the time-dependent semiclassical transport theory and shows that the induced nonequilibrium conduction spin density generates four spin torques acting on the magnetization.

Relativistic theory of magnetic inertia in ultrafast spin dynamics
The influence of possible magnetic inertia effects has recently drawn attention in ultrafast magnetization dynamics and switching. Here we derive rigorously a description of inertia in the
