Origami is a popular method to design building blocks for mechanical metamaterials. Here, the authors assemble a volumetric origami-based structure, predict its axial and rotational movements during folding, and demonstrate the operation of mechanical one- and two-bit memory storage.
The deterministic nucleation of single skyrmions at a controlled position along multilayered magnetic racetracks is demonstrated by exploiting spin-orbit torques without the need of in-plane magnetic fields.
Time-resolved X-ray microscopy reveals the mechanism and speed of current-induced magnetization switching of Co/Pt dots under the combined effect of spin-orbit torques and Dzyaloshinskii–Moriya interaction.
