Control over spin transport in antiferromagnetic systems is essential for future spintronic applications with operational speeds extending to ultrafast time scales. A consortium of physicists at SPINTEC, JGU Berlin and Charles University Prague established the essential role of interfaces for spin current injection and spin current-to-charge current conversion, from the gigahertz (GHz) diffusive to […]

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 […]

Context: CEA has recently committed to an ambitious, long-term, EU-driven research project focused on materials innovation in order to implement green and digital transitions in a sustainable way and inclusive for society. The accelerated development of 2D materials answers the need for innovative spintronics with controlled amounts of materials. An essential aspect is getting closer […]

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 […]

A new form of spintronic is emerging, exploiting electrical insulators. Recent spectroscopic studies performed at SPINTEC have revealed the coherent coupling that may establish between two distant macrospins separated by a non-magnetic dielectric spacer via circularly-polarized acoustic phonons that carry angular momentum information. This long-range effect represents an important progress in magnonics and spin wave […]
