  • Magnetic vortices in thin ferromagnetic films possess a core with out-of-plane magnetization whose polarity can be manipulated by magnetic fields or currents for technological applications. Here, the authors demonstrate local control of the core polarity in NiFe films via an imprinted maze domain pattern.

  • Artificial spin ices are composed of tiny magnets arranged in a lattice. Despite their simplicity, they exhibit rich dynamic magnetic behaviour. Here, Lendinez et al demonstrate that, like continuous magnetic thin films, artificial spin ices can exhibit non-linear magnon-magnon scattering which, in conjunction with their reconfigurability, offers great potential for tuneable magnon transport.

  • Three-dimensional structures of vortex loops in a bulk micromagnet GdCo2 have been observed using X-ray magnetic nanotomography. The cross-section of these loops consists of a vortex–antivortex pair stabilized by the dipolar interaction.

  • Artificial magnetic nanostructures enable the study of competing frustrated interactions with more control over the system parameters than is possible in magnetic materials. Farhan et al. present a two-dimensional lattice geometry where the frustration can be controlled by tuning the unit cell parameters.

  • Techniques exist for imaging the magnetization patterns of magnetic thin films and at the surfaces of magnets, but here hard-X-ray tomography is used to image the three-dimensional magnetic structure within a micrometre-sized magnet in the vicinity of Bloch points.

  • Knowledge and control of the dynamic response in micromagnetic configurations is important both for understanding their fundamental properties and for their use in technological applications. Pump–probe magnetic laminography now unveils the evolution of the magnetization in a three-dimensional system with nanoscale resolution.
