Chiral Damping-Induced Chirality Switching and Control of Domain Walls in Antiferromagnets
Collins Ashu Akosa, Mu-Kun Lee, Aurélien Manchon +1
We investigate the impact of chiral damping (CD) on current-driven domain-wall (DW) dynamics in antiferromagnets (AFMs). Asymmetric CD between sublattices generates off-diagonal co…
Exact Solution for Current-Driven Domain-Wall Dynamics Beyond Lorentz Contraction in Antiferromagnets with Dzyaloshinskii-Moriya Interaction
Mu-Kun Lee, Rubén M. Otxoa, Masahito Mochizuki
We study current-driven domain-wall (DW) dynamics in antiferromagnets (AFMs) with Dzyaloshinskii-Moriya interaction (DMI). We obtain an exact analytical solution for spiral DW dyna…
Skyrmion Hall effect and shape deformation of current-driven bilayer skyrmions in synthetic antiferromagnets
Mu-Kun Lee, Javier A. Vélez, Rubén M. Otxoa +1
The commonly believed absence of skyrmion Hall effect for topologically trivial magnetic skyrmions is reconsidered for bilayer skyrmions in synthetic antiferromagnets driven by spi…
Predicted Multiple Walker Breakdowns for Current-Driven Domain-Wall Motion in Antiferromagnets
Mu-Kun Lee, Rubén M. Otxoa, Masahito Mochizuki
We theoretically discover possible emergence of reentrant Walker breakdowns for current-driven domain walls in layered antiferromagnets in striking contrast to the unique Walker br…
Handwritten Digit Recognition by Spin Waves in a Skyrmion Reservoir
Mu-Kun Lee, Masahito Mochizuki
By performing numerical simulations for the handwritten digit recognition task, we demonstrate that a magnetic skyrmion lattice confined in a thin-plate magnet possesses high capab…
Reservoir Computing with Spin Waves in Skyrmion Crystal
Mu-Kun Lee, Masahito Mochizuki
Magnetic skyrmions are nanometric spin textures characterized by a quantized topological invariant in magnets and often emerge in a crystallized form called skyrmion crystal in an…
