Phenomenology of current-induced dynamics in antiferromagnets

KMD Hals, Y Tserkovnyak, A Brataas - Physical review letters, 2011 - APS
We derive a phenomenological theory of current-induced staggered magnetization
dynamics in antiferromagnets. The theory captures the reactive and dissipative current …

Theory of current-driven magnetization dynamics in inhomogeneous ferromagnets

Y Tserkovnyak, A Brataas, GEW Bauer - Journal of Magnetism and …, 2008 - Elsevier
We give a brief account of recent developments in the theoretical understanding of the
interaction between electric currents and inhomogeneous ferromagnetic order parameters …

Current-induced torques in continuous antiferromagnetic textures

AC Swaving, RA Duine - Physical Review B—Condensed Matter and Materials …, 2011 - APS
We study the influence of an electric current on a continuous noncollinear antiferromagnetic
texture. Despite the lack of a net magnetic moment, we find that the exchange interaction …

Staggered dynamics in antiferromagnets by collective coordinates

EG Tveten, A Qaiumzadeh, OA Tretiakov, A Brataas - Physical review letters, 2013 - APS
Antiferromagnets can be used to store and manipulate spin information, but the coupled
dynamics of the staggered field and the magnetization are very complex. We present a …

Inertia-free thermally driven domain-wall motion in antiferromagnets

S Selzer, U Atxitia, U Ritzmann, D Hinzke, U Nowak - Physical Review Letters, 2016 - APS
Domain-wall motion in antiferromagnets triggered by thermally induced magnonic spin
currents is studied theoretically. It is shown by numerical calculations based on a classical …

Dynamics of antiferromagnets driven by spin current

R Cheng, Q Niu - Physical Review B, 2014 - APS
When a spin-polarized current flows through a ferromagnetic (FM) metal, angular
momentum is transferred to the background magnetization via spin-transfer torques. In …

Current-induced magnetization dynamics in disordered itinerant ferromagnets

Y Tserkovnyak, HJ Skadsem, A Brataas… - Physical Review B …, 2006 - APS
Current-driven magnetization dynamics in ferromagnetic metals is studied in a self-
consistent adiabatic local-density approximation in the presence of spin-conserving and …

High antiferromagnetic domain wall velocity induced by Néel spin-orbit torques

O Gomonay, T Jungwirth, J Sinova - Physical review letters, 2016 - APS
We demonstrate the possibility to drive an antiferromagnetic domain wall at high velocities
by fieldlike Néel spin-orbit torques. Such torques arise from current-induced local fields that …

Current-induced torques due to compensated antiferromagnets

PM Haney, AH MacDonald - Physical review letters, 2008 - APS
We analyze the influence of current-induced torques on the magnetization configuration of a
ferromagnet in a circuit containing a compensated antiferromagnet. We argue that these …

Spin-transfer torques in antiferromagnetic metals from first principles

Y Xu, S Wang, K Xia - Physical review letters, 2008 - APS
In spite of the absence of a macroscopic magnetic moment, an antiferromagnet is spin-
polarized on an atomic scale. The electric current passing through a conducting …
