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…

Nonreciprocal transport in a room-temperature chiral magnet
Daisuke Nakamura, Mu-Kun Lee, Kosuke Karube +4
Chiral magnets under broken time-reversal symmetry can give rise to rectification of moving electrons, called nonreciprocal transport. Several mechanisms, such as the spin-fluctuat…
