Magnetic skyrmions are magnetic nanobubbles which are envisioned as bits of informations in our computers. A team from the Spintec laboratory in Grenoble has demonstrated that they can be moved by electric current at record speeds, up to 900 m/s, in antiferromagnetic stacks. These results hold promise for the use of skyrmions to store and […]

Magnetic skyrmions are appealing for use in logic and memory devices combining small size and fast motion. Here, we propose to exploit skyrmion interactions to perform both logic and memory operations at the nanoscale. Our concept opens a path for novel devices which intrinsically merge high-density non-volatile data storage with computing capabilities. a. Schematic representation […]

Magnetic skyrmions are localized chiral spin textures, which offer great promise to store and process information at the nanoscale. The unique sense of rotation of their surrounding domain wall, called chirality, is resulting from the so-called Dzyaloshinskii−Moriya Interaction. C.E. Fillion et al. have managed the inversion of the skyrmion chirality by applying a gate voltage, […]

Skyrmions in synthetic antiferromagnets are appealing for use in future memory and computing devices, combining small size and fast motion, but creating, stabilizing, and observing them remains a challenge. Here, we demonstrate the stabilization and current and light induced nucleation of skyrmions in a synthetic antiferromagnet, observing the magnetization texture in each layer using X-ray […]
