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 […]

You find here the list of proposals for Master-2 internships to take place at Spintec during Spring 2023. In most cases, these internships are intended to be suitable for a longer-term PhD work. Interested Master-1 students are also encouraged to apply, as well as students not phased for a Spring internship, especially those coming from […]

The rapid development of information technology (IT) has had profound consequences on most aspects of our civilization. However, the energy consumption associated to IT continues to rise at an accelerated pace. In this context the microelectronics industry faces major challenges related to power dissipation and energy consumption. A promising solution is the integration of non-volatile […]

Magnetic skyrmions are local twists of the magnetization which hold promise as nm scale information carrier. Here we demonstrate that focused He+-ion irradiation can be used to create and guide skyrmions in magnetic tracks. This work opens up a new path to manipulate magnetic skyrmions in magnetic memory and logic devices. Magnetic skyrmions are currently […]

The research highlights of SPINTEC over the year 2020 have been put together, and are available to download: https://www.spintec.fr/spintec-annual-booklets. This booklet contains the key facts of the lab over the period (contracts, new staff etc.), the most up-to-date description of the lab activity and the research teams. We wish you a nice reading!

Non-volatility is the main physical feature that fast memories, such as SRAM, are still lacking. Such memories could increase computing performance while reducing significantly the power consumption. The only viable option for sub-ns nonvolatile memory is the Spin-Orbit Torque Magnetic Random Access Memory (SOT-MRAM). The main roadblock towards the integration of the SOT-MRAM is that […]
