  • Skyrmions are topological two-dimensional spin textures that in three-dimensional systems resemble strings or tubes. Here, using transmission electron microscopy Zheng et al observe the braiding of skyrmion strings in FeGe and predict this phenomenon for a large family of magnets.

  • The authors study the dynamics of 80 nm-size skyrmions in a 100 nm-wide track by electrical Lorentz transmission electron microscopy. They show that the skyrmions can be moved by nanosecond current pulse without experiencing the skyrmion Hall effect.

  • Transmission electron microscopy is used to observe three-dimensional topological solitons known as hopfions that in a chiral magnet are found to form rings around skyrmion strings, and a nucleation protocol for these rings is provided.

  • When strain is applied to some magnetic materials, the magnetic properties and magnetization can change drastically. This coupling is referred to as magnetoelasticity, and while its history of study is long, it is still not a well-understood phenomenon. In this work, Kong et al. shed light on magnetoelasticity using a variety of experimental probes.

  • Proposals for skyrmion-based high-density memory devices require an understanding of the formation and shape of skyrmions in confined geometries. Here, the authors use electron holography to image magnetic textures in FeGe nanostripes and explore the parameters governing skyrmion morphology.

  • Crystallographic dislocation has proven harmful to the carrier dynamics in conventional semiconductors but it is unexplored in metal halide perovskites. Here Jiang et al. grow remote epitaxial perovskite films on graphene with density-controlled dislocations and confirm their negative impact.

  • Magnetic skyrmions—a type of localized spin texture—have been theoretically predicted to annihilate with counterparts known as antiskyrmions. By means of electron microscopy, such annihilation has now been observed in a cubic chiral magnet.
