Spin-charge conversion phenomena harnessing the spin orbit coupling are promising for the future of spintronics, allowing in one way (charge–to-spin) the generation of torque on magnetic elements and in the other way (spin-to-charge) the detection of spin current for spin logic or neuromorphic operations. We report a highly tunable and record spin-to-charge conversion in a […]

Following a PhD and post-doc period in Grenoble, he further developed his expertise and carrier during ten years as CNRS research scientist. He has been working in CEMES (Toulouse), one of the craddles of French electron microscopy. Aurélien joined Spintec […]

MILF stands for Magnetic Imaging at Low dimensions & high Frequencies. It is a 36-month-long early-carrier ANR project. Magnetic events such as domain reversal, domain wall propagation and vortex oscillations are fast processes, broad source of spintronic applications. However, it remains extremely challenging to scrutinize the inner structure of such magnetic objects during their motion, […]

In the field of spintronics, ferromagnetic/non-magnetic metallic multilayers are core building blocks for emerging technologies. Resonance experiments using stripline transducers are commonly used to characterize and engineer these stacks for applications. Here, we investigated the incompletely understood impact of eddy currents below the microwave magnetic skin-depth and explained the lineshape asymmetry and phase lags reported […]

On Wednesday September 25 at 11:00 we have the pleasure to welcome Prof. Jian-Ping WANG (University of Minnesota, MN, USA). He will give us a seminar at CEA/IRIG, Bat 1005, room 445 entitled : Computing using magnetic random access memory (CRAM) and spin-orbit torque (SOT) memory cell To enable local or edge AI like family-based […]

Internet of Things (IoT) applications deployment relies on low-power and security constraints. In this perspective, lightweight cryptography has been developed. This field enables, with a reduced area and power consumption, to encrypt sensitive data processed in an integrated circuit and transmitted to a connected object. This work proposes to implement the PRESENT lightweight cryptographic algorithm […]

Olivier Fruchart, Deputy Director of Spintec, has been elected Vice-President of the European Magnetism Association for a three-year mandate, alongside Burkard Hillebrands from Kaiserslautern, elected President. The purpose of the European Magnetism Association (EMA) is to promote the development of magnetism and magnetic materials in Europe, through rising the visibility and the impact of research […]

Numerous studies investigated the use of synthetic membranes for photonic or biomedical applications. We report here on a recent type of biocompatible magnetically actuated membranes, partly originating from studies on magnetic particles for biology, consisting of PDMS/Au bilayers with embedded arrays of micrometric magnetic pillars. Flat at zero field, concave in an applied magnetic field, […]

Domain wall propagation in modulated-diameter cylindrical nanowires is a key phenomenon to be studied with a view to designing three-dimensional magnetic memory devices. In this framework, we quantified theoretically the driving force needed for a domain wall to overcome the potential barrier related to modulated diameter geometry in order to jump from one stable position […]
