Manipulation of skyrmion motion by magnetic field gradients
Nature Communications, 2018 Manipulation of skyrmions is one of the keys to achieving the skyrmion based spintronic devices. Here the authors show the skyrmions in Cu2OSeO3 can be rotated collectively with fixed velocity–radius relationship under a static magnetic field gradient ...

Journal of High Energy Physics, 2008 Skyrme chains are topologically-nontrivial solutions of the Skyrme model which are (quasi-)periodic in one spatial direction. We report numerical and analytic investigations which show that such solutions exist. Chains of 1-skyrmions are reasonably well approximated both as parallel vortex-antivortex pairs, and in terms of the holonomy of Yang-Mills ...

Advanced Science, EarlyView.A fully compensated synthetic antiferromagnet (SAF) multilayer exhibits a uniform state at zero field, without skyrmions. We use a SAF bias system to provide RKKY‐mediated exchange bias to the SAF multilayer, promoting zero‐field skyrmion stabilization and polarity control.

Polarization Dynamics in Ferroelectrics: Insights Enabled by Machine Learning Molecular Dynamics
Advanced Science, EarlyView.Machine learning molecular dynamics is presented as a route to capture polarization switching, domain wall kinetics, topological polar textures, and polar mechanical coupling beyond the limits of conventional atomistic methods. This Perspective surveys recent progress and identifies key methodological directions, including long‐range electrostatics ...

Lattices of Generalized Skyrmions [PDF]
, 2011 Generalized Skyrme systems are those which include both the Skyrme and the Skyrme-Faddeev models through an interpolating parameter \alpha \in [0,1] the former corresponds to \alpha=0 and the latter to \alpha=1.

Sculpting liquid crystal skyrmions with external flows
Physical Review Research, 2023 We investigate, using experiments and numerical simulations, the distortions and the alignment of skyrmions in liquid crystal under external flows for a range of average flow velocities.

Advanced Science, EarlyView.Co doping in Mn3Sn transforms the spin texture magnetic state from a coplanar noncollinear magnetic state into a noncoplanar one, resulting in a large topological Hall effect (THE) over a wide temperature range (2–300 K). The THE arises from a noncoplanar spin texture, driven by lattice distortion and enhanced out‐of‐plane Dzyaloshinskii ...
