Laser-induced topological spin switching in a 2D van der Waals magnet

Nature Communications, 2023
Van der Waals magnetic materials, which maintain their magnetic ordering down to a monolayer have been found to host a variety of spin textures, including topological spin textures such as skyrmions. Here, Khela et al.

Magnetic Skyrmions Under Confinement

Communications in Mathematical Physics, 2023
AbstractWe present a variational treatment of confined magnetic skyrmions in a minimal micromagnetic model of ultrathin ferromagnetic films with interfacial Dzylashinksii-Moriya interaction (DMI) in competition with the exchange energy, with a possible addition of perpendicular magnetic anisotropy. Under Dirichlet boundary conditions that are motivated

Bloch-type photonic skyrmions in optical chiral multilayers

Physical Review Research, 2021
Magnetic skyrmions are topological quasiparticles in magnetization. Recently, as one of their photonic counterparts, Néel-type photonic skyrmions were discovered in evanescent electromagnetic waves.

Manipulation of Magnetic Skyrmion Density in Continuous Ir/Co/Pt Multilayers

Micromachines, 2022
We show that magnetic skyrmions can be stabilised at room temperature in continuous [Ir/Co/Pt]5 multilayers on SiO2/Si substrates without the prior application of electric current or magnetic field.

Blowing magnetic skyrmion bubbles [PDF]

Science, 2015
Skyrmions emerge in trilayers Skyrmions are tiny whirlpools of magnetic spin with potential to act as carriers of information in future devices. Skyrmions have been observed in multiple materials but usually at impractically low temperatures. Jiang et al.

Analog Control of Reconfigurable GHz Resonances from Chiral Spin Texture Ensembles. [PDF]

Adv Mater
Tunable microwave components ‐ essential for wireless technology ‐ typically require costly, customized nanofabrication. We show that ambient spin texture ensembles (e.g., magnetic skyrmions) in chiral multilayer films can enable reconfigurable microwave resonators.

Skyrmions in magnetic multilayers [PDF]

Physics Reports, 2017
Symmetry breaking together with strong spin-orbit interaction give rise to many exciting phenomena within condensed matter physics. A recent example is the existence of chiral spin textures, which are observed in magnetic systems lacking inversion symmetry.

Magnetic Skyrmionic Polarons [PDF]

Nano Letters, 2017
We study a two-dimensional electron gas exchanged-coupled to a system of classical magnetic ions. For large Rashba spin-orbit coupling a single electron can become self-trapped in a skyrmion spin texture self-induced in the magnetic ions system. This new quasiparticle carries electrical and topological charge as well as a large spin, and we named it as

Enhancement of skyrmion density via interface engineering

APL Materials, 2023
Magnetic skyrmions are promising candidates for computing and memory applications. The static and dynamic behaviors of skyrmions are tunable by altering the interfacial magnetic properties. These interfacial magnetic properties are alterable by modifying

A spin model for intrinsic antiferromagnetic skyrmions on a triangular lattice

Frontiers in Physics, 2023
Skyrmions are prospected as the potential future of data storage due to their topologically protected spin structures. However, traditional ferromagnetic (FM) skyrmions experience deflection when driven with an electric current, hindering their usage in ...
