The scattering of baby Skyrmions off potential obstructions, in a Landau-Lifshitz model [PDF]

, 2009
The dynamics of baby skyrmions of the (2+1) new baby Skyrme model, in a Landau - Lifshitz model, was studied in the presence of various potential obstructions of varying geometries.

Magnetic skyrmion stabilization, nucleation, and dynamics on magnetic multilayer thin films

, 2021
Magnetic skyrmions are particle-like nanoscale magnetic structures currently surging in interest in the spintronics field. Their small size combined with topological stability and efficient manipulation by various electromagnetic excitations make them ...

Phenomenology of current-induced skyrmion motion in antiferromagnets

New Journal of Physics, 2016
We study current-driven skyrmion motion in uniaxial thin film antiferromagnets in the presence of the Dzyaloshinskii–Moriya interactions and in an external magnetic field.

Light‐Modulated Exchange Bias in Multiferroic Heterostructures

Electron, EarlyView.
In this article, exchange bias and magnetization are modulated with visible light at room temperature in PMN‐PZT/FeGa/IrMn multiferroic heterostructures. Photostrictive effect is the main mechanism leading to the modulation of magnetic anisotropy and interfacial exchange bias coupling between the ferromagnetic and antiferromagnetic layers.

Skyrmion morphology in ultrathin magnetic films

, 2018
Nitrogen-vacancy magnetic microscopy is employed in quenching mode as a non-invasive, high resolution tool to investigate the morphology of isolated skyrmions in ultrathin magnetic films.

A Polar Topology Network Induces Elastic Stiffening in Ferroelectric Oxide Superlattices

Small, EarlyView.
The periodicity in BiFeO3/SrTiO3 superlattices tunes the system into a dense, elastically constrained polar texture state. This topology‐rich regime reveals a collective mechanical response in which interactions among polar topological defects restrict local deformations, producing a pronounced elastic stiffening.

Discontinuous to continuous transition changeover and magnetic helicity reversal in helimagnet nanodisks under torsion

New Journal of Physics
A magnetic skyrmion is topologically protected because it possesses a non-zero topological charge. As a result, the creation or annihilation of a magnetic skyrmion is thought to be initiated by a sudden reversal of local magnetization, and thus cannot ...

Target-skyrmions and skyrmion clusters in nanowires of chiral magnets

EPJ Web of Conferences, 2014
In bulk non-centrosymmetric magnets the chiral Dzyaloshinskii-Moriya exchange stabilizes tubular skyrmions with a reversed magnetization in their centers.
