  • Magnetic droplets occur in nanocontact spin-torque oscillators with perpendicular anisotropy, forming part of a family of particle-like magnetic objects, which may be excited for high-frequency applications. Here, the authors determine a current–field phase diagram for magnetic droplet nucleation.

  • This study presents a method to create nanoscale polarization transient gratings in the EUV range. Unlike intensity gratings, it reduces thermal effects, revealing hidden material dynamics. This enables new insights in chiral materials and ultrafast magnetism.

  • Extending magnetic nanostructures into three dimensions offers a vast increase in potential functionalities, but this typically comes at the expense of ease of fabrication and measurement. Here, Dion et al. demonstrate an approach to creating three dimensional magnetic nanostructures while retaining easy fabrication and readout of established two dimensional approaches.

  • 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.

  • Topological magnetic monopoles are non-local spin textures that are robust to thermal and quantum fluctuations, but they are difficult to study at the nanoscale in real space. Now, soft X-ray vector ptycho-tomography is demonstrated to determine the three-dimensional magnetization vector and emergent magnetic field of such magnetic monopoles in a ferromagnetic meta-lattice.

  • Memristors are reconfigurable devices that are switchable between low and high resistive states and are expected to play an important role in the integrated circuit technology of next generation computing. Here, the authors theoretically demonstrate that ring-shaped nanostructures composed of a ferromagnetic material can exhibit memristive properties with performance values in the GHz range.
