The 2026 Skyrmionics Roadmap

TL;DR

The 2026 Skyrmionics Roadmap synthesizes theory, material platforms, dynamics, and device concepts to chart how magnetic skyrmions and related topological textures can transition from fundamental phenomena to technology. It foregrounds 3D topologies such as Hopfions and antiskyrmions, and leverages inverse micromagnetics, noncommutative geometry, and quantum descriptions to unify real-space textures with electronic structure. Core contributions include frameworks for topology in 3D, rigorous stability analyses under nonequilibrium conditions, and comprehensive surveying of imaging, readout, and control strategies across ferromagnetic, ferrimagnetic, and antiferromagnetic platforms. Practical impact centers on robust detection, deterministic nucleation, reduced-power manipulation, and integration pathways toward skyrmion-based memories, neuromorphic computing, and magnonic devices. Collectively, the Roadmap delineates the challenges and opportunities to realize 3D spintronic architectures through materials design, advanced imaging, and differentiable micromagnetics enabling real-time optimization and closed-loop experiments.

Abstract

Magnetic skyrmions and related topological spin textures have emerged as a central topic in condensed-matter physics, combining fundamental significance with potential for transformative applications in spintronics, magnonics, and beyond. Over the past decade, advances in material platforms, imaging techniques, theoretical modeling, and device concepts have established skyrmionics as a rapidly expanding field. At the same time, challenges remain in stabilizing, controlling, and integrating such textures into functional architectures, while novel phenomena such as antiskyrmions, higher-order skyrmions, hopfions, and antiferromagnetic textures arise. The 2026 Skyrmionics Roadmap represents a collective effort of many authors, providing a comprehensive perspective on the current state-of-the-art and the outlook for the coming years. In 33 focused sections, each co-authored by two researchers, we chart progress in theory and modeling, material systems, skyrmion dynamics, and skyrmion technologies. By offering a consolidated vision, this Roadmap aims to guide both fundamental research and application-driven efforts, accelerating the transition of skyrmionics from conceptual breakthroughs toward practical technologies.

• Figure 2: The four main thematic sections addressed in this roadmap and the topical keywords discussed by the individual sections.
• Figure 3: Reconstruction of a skyrmion structures from magnetic stray-field data. The top volume illustrates the measured vertical stray field component $H_z$, which is used as input to an inverse problem. The lower plane shows the reconstructed in-plane magnetization distribution obtained via a physics-informed optimization process. The inverse solution accurately recovers the characteristic circular structure of Néel-type skyrmions.
• Figure 4: Roadmap for 3D magnetic-texture-based technologies, illustrating the interplay between theoretical and experimental efforts across three key stages: Creation, Manipulation, and Technology. The double helix represents the intertwined progress of Theory (left) and Experiment (right). Colored markers indicate stages of progress: green (established), yellow (beginning), and red (unexplored).
• Figure 5: Topological transitions via mixed topology states. Colors represent the magnetization direction $\mathbf{m}$ as indicated in the legend at the right. Top row: Transition from a Skyrmion to a Ferromagnet via intermediate states such as a Meron. Bottom row: Evolution from a Hopfion to a Skyrmion tube through a Twiston---a screw dislocation configuration Azhar2022. The inset on the far left depicts a Hopfion with a more internal $m_z$ isosurface, illustrating the linking of two field lines of the emergent magnetic field $\mathbf{F}$. These transitions can be conceptually understood as analogous to peeling an onion—removing successive "layers" (isolines for Skyrmions and isosurfaces for Hopfions) while preserving the inner structure until reaching a topologically simpler configuration.
