Context: In the frame of the Chirex project of the PEPR Spin, Spintec laboratory is opening a postdoctoral researcher position. The candidate will work on ultrathin magnetic heterostructures hosting skyrmions and deposited by magnetron sputtering at Spintec, and will use them to explore the combination of gate voltage and ultrafast laser pulses to control skyrmion […]

The large magnetometers currently used onboard satellites for space exploration cannot be installed in the tiny nanosatellites (cubesat) that are envisioned for multipoint measurements. As a first step towards the realization of a miniature space magnetometer, Spintec has demonstrated a strong amplification of the sensitivity of a magnetic field sensor on chip. The current magnetometers […]

On Friday October 13th 2023, we have the pleasure to welcome in SPINTEC Diana C Leitao (Eindhoven University of Technology, The Netherlands) and Shunsuke Fukami (Tohoku University, Japan). They will give us two seminars on magnetoresistive sensors and magnetic tunnel junctions from 10:00 to 12:00. Place : IRIG/SPINTEC, auditorium 445 CEA Building 10.05 (access to […]

Position: Skyrmions are circular magnetic domains of (sub-)micron size with increasing interest to the scientific community, considering to use them for information encoding. The aim of this thesis is to exploit the potential of skyrmions in a new way: developing a magnetic field sensor. Indeed, the response of skyrmions to the magnetic field perpendicular to […]

MAROT stands for Low noise MAgnetometeR based On Tunnel junctions. It is a 42-months long ANR project (ANR-22-CE42-0020). The current boom in nanosatellites, which are revolutionizing space exploration, calls for the development of suitable miniature instruments. In particular, the extremely high-performance magnetometers used to date on-board satellite, such as search-coils or flux-gates, are heavy and […]

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, […]
