From Topological and Chiral Magnetism for Next-Generation Information Devices
Recent advances in topological and chiral magnetism are creating new opportunities for energy-efficient, ultrafast, and scalable information technologies. Magnetic skyrmions, antiskyrmions, chiral domain walls, spin textures, and topological spin excitations in low-dimensional and quantum materials offer novel approaches to data storage, logic, sensing, and neuromorphic computing. Progress in materials synthesis, interface engineering, spin-orbit coupling control, and advanced characterization is accelerating the realization of robust topological magnetic states in device-relevant platforms.
This Special Topic highlights emerging developments in materials, physics, and device concepts underpinning topological and chiral magnetism for next-generation information technologies. We welcome experimental, theoretical, and computational studies on magnetic materials discovery, heterostructures, 2D and van der Waals magnets, noncollinear spin textures, spin transport, ultrafast dynamics, chirality control, topology-driven functionalities, and innovative device architectures. Contributions addressing scalable fabrication, operando characterization, machine learning, and integration with CMOS or quantum technologies are particularly encouraged.
The issue aims to provide a multidisciplinary forum linking fundamental discoveries with future spintronic and information-processing applications.
Topics covered include, but are not limited to:
- Magnetic skyrmions, antiskyrmions, and 3D topological spin textures (e.g., hopfions)
- Spin–orbit coupling and interfacial chirality engineering
- Chiral domain walls and Dzyaloshinskii–Moriya interactions
- Spin transport phenomena, spin Hall effects, and spin caloritronics
- Topological magnetic materials and quantum magnets
- Ultrafast spin dynamics and femtosecond magnetism
- 2D, van der Waals, and low-dimensional magnetic systems
- Antiferromagnetic and ferrimagnetic spintronics
- Neuromorphic, probabilistic, and unconventional spin-based computing devices
- Topological magnetism for memory, logic, and quantum information technologies
