A GMR Heads oral history panel was held at the Computer History Museum, Mountain view, California, in May 2019. It celebrated the introduction of giant magnetoresistance (GMR) heads in hard disk drives in 1997, which has been a key is sustaining the growth rate of areal density in magnetic recording. The panel featured four colleagues […]

Spin Orbit Torque Magnetic RAM (SOT-MRAM) approach represents a new way to overcome Spin Transfer Torque (STT) memory limitations by separating the reading and the writing paths. It is particularly interesting for high-speed applications that do not require very high density because of two transistors per bit cell. This work introduces a high-density SOT-MRAM memory […]

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 […]

Aurélien Masseboeuf is a recognized expert in transmission electron microscopy techniques applied to magnetic microscopy. 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 […]
