Magnetic heliknotons are hopfions embedded in helical spin backgrounds. Current-induced nucleation and Hall-effect-free motion of isolated magnetic heliknotons is demonstrated in the chiral magnet FeGe.

A major bottleneck in the use of machine learning in materials discovery is the need for high quality material datasets for training. Here, Itani and coauthors introduce NEMAD, the northeast materials database, collated from the scientific corpus of articles using Large Language Model to extract the relevant magnetic, crystallographic and chemical data.

The recent experimental creation of magnetic skyrmions, topologically protected particle-like spin textures, has inspired proposals for their application in nanodevices. Here, the authors use Lorentz transmission electron microscopy to demonstrate edge-mediated skyrmion chain formation in FeGe nanostripes.

There has been much interest in using skyrmions for new approaches to compution, however, creating, deleting and driving skyrmions remains a challenge. Here, Wang et al demonstrate all three operations for skyrmions in tailored Co8Zn10Mn2 nanodevices using tailored current pulses.

Strong magnetic interfacial coupling in van der Waals heterostructures provides a new platform for discovering novel physics and effects. Here, the authors report the formation of skyrmion lattice in the WTe₂/Fe₃GeTe₂ van der Waals heterostructure and a Dzyaloshinskii–Moriya interaction with a large energy density of 1.0 mJm⁻².

Cobalt ions in different sublayers of the double-layered Ruddlesden–Popper perovskite Sr₃Co₂O₇ are found to develop inequivalent ionic displacements, geometrically generating a polar state while preserving metallic conductivity and exhibiting antiferromagnetism.

The authors synthesize intrinsic room-temperature ferroelectric CuVP₂S₆ via spatially confined chemical vapor deposition method, uncovering the ferroelectric mechanism, which originates from the movement of Cu ions.

The coexistence of chiral edge states and chiral spin textures in magnetic topological insulator sandwiches provides a platform for proof-of-concept dissipationless spin-textured spintronic applications.

The real-space magnetic configurations of a zero-dimensional skyrmionic vortex structure is uncovered using electron holography and micromagnetic simulations.

The authors report coexisting ferromagnetism, polar distortion and metallicity in quasi-two-dimensional Ca₃Co₃O₈, providing a platform to exploit magnetoelectric coupling in a metallic system.

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.

Future magnetic memory technologies may be based on the manipulation of skyrmions, nanoscale topologically stable circulating magnetization textures arising in chiral magnets. Here, the authors explore the behaviour of skyrmion clusters in nanowires with widths comparable to the single-skyrmion scale.

Non-trivial topological magnetic textures, such as skyrmions, merons or vortices, possess topological charges Q with absolute values smaller or equal to one. Now, skyrmion bundles, multi-Q three-dimensional skyrmionic textures, are observed and their current-driven dynamics are studied.

Ionic substitution is a useful way to manipulate structural, electronic, magnetic phase transitions in strongly correlated materials. Here, the authors report electric-field controlled protonation in SrRuO₃, resulting in a large structural expansion and a ferromagnetic-to-paramagnetic phase transition.
