Researchers at SPINTEC Grenoble, in collaboration with PHELIQS & CIME Grenoble and LOMA Bordeaux, demonstrated how the superconducting proximity effect can be used to evaluate the penetration of Cooper pairs in metallic antiferromagnets. These findings represent a stimulating example of how antiferromagnets and superconductors may envision a common future by showing how to infer essential […]

In the frame of the French national ANR project ELMAX, Spintec laboratory is opening a postdoctoral researcher position. The candidate will work on the magnetism of FexGeTe2 2D ferromagnets grown by molecular beam epitaxy. The objective will be to tune the magnetic properties of 2D ferromagnets by interfacing with high spin-orbit materials (transition metal dichalcogenides […]

This study investigates heavy-ion irradiation effects on Perpendicular Magnetic Anisotropy Spin-Transfer Torque Magnetic Tunnel Junction devices (p-STT-MTJs). The radiative campaign took place at the Cyclotron Resource Centre of Université Catholique de Louvain (UCL).   Designers of space systems have to deal with ensuring complex data processing, while obtaining, at the same time, a proper level […]

We have conducted time-resolved stroboscopic imaging of the magnetization dynamics in cylindrical nanowires subject to nanosecond pulses of electric current. These confirm the dramatic impact of the Œrsted field in the cylindrical geometry. Through a thorough quantitative analysis, we extract features during the pulse of current, such as the azimuthal component of magnetization in magnetic […]

Using a macrospin approach, we carried out a systematic analysis of the role of the voltage controlled magnetic anisotropy on the magnetization dynamics of nanostructures with out-of-plane magnetic anisotropy. Diagrams of the magnetization switching have been computed depending on the material and experiment parameters thus allowing predictive sets of parameters for optimum switching experiments. Voltage […]

NeuSPIN – An ANR project

NeuSPIN stands for Design of a reliable edge neuromorphic system based on spintronics for Green AI. Current computing architectures with separate processing and memory blocks are not ideal for energy-efficient learning and inference processing for AI on the edge concept. For AI edge applications, it is envisioned that classical von Neumann computing will be replaced […]

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 […]

We report a theoretical overview of the magnetic domain wall behavior under an electric current in infinitely long nanotubes with azimuthal magnetization. We highlight effects that, besides spin-transfer torques already largely understood in flat strips, arise specifically in the tubular geometry: the Œrsted field and curvature-induced magnetic anisotropy resulting both from the exchange interaction and […]
