We demonstrate that single pulse all optical helicity independent switching can be generalized for a large range of rare earth–transition metal multilayers. The threshold fluence for switching is observed to be independent of the pulse duration and, at high laser intensities, concentric ring domain structures are induced, unveiling multiple fluence thresholds. These striking switching features […]

We demonstrate that a perpendicular magnetic tunnel junction (MTJ) is capable of emulating an artificial spiked neuron. The magnetic stack has been designed so that the MTJ has two free layers, whose magnetization can be driven in a windmill-like dynamic by the spin transfer torque. The output-spiking rate is tunable by the dc bias voltage. […]

Spintec laboratory is opening a up-to three years engineer researcher position in the framework of the PEPR electronics (part of France 2030 strategy) – project EMCOM (emerging memories for computing).   Context: The cost of transferring information between different layers of storage and computing units now domi-nates the energy performance of conventional processors. This has […]

Nuno CACOILO will defend his PhD thesis entitled : Fundamentals of ultrascaled 3D magnetic tunnel junctions and integration routes for high density memory arrays Place : SPINTEC, CEA Building 10.05, auditorium 445 (access needs authorization *) ZOOM link : https://univ-grenoble-alpes-fr.zoom.us/j/5115826964 Abstract : The perpendicular Spin Transfer Torque Magnetic […]

Le ministère de l’enseignement supérieur et de la recherche a dressé le portrait de plusieurs lauréats ERC en France. Bernard Dieny, chercheur en électronique de spin à SPINTEC dans l’équipe MRAM, est l’un d’entre eux. Le domaine d’expertise de Bernard Dieny couvre un large spectre qui va de la recherche fondamentale en nanomagnétisme et en […]

On Monday, September 18th 2023, we have the pleasure to welcome in SPINTEC Yoichiro Tanaka from Tohoku University, Japan. He will give us a seminar at 14:00, entitled : Magnetic data storage technology; from the invention of perpendicular magnetic recording (PMR) to the social integration Place : IRIG/SPINTEC, auditorium 445 CEA Building 10.05 (access to […]

A new type of magnetic sensor based on the spin transfer torque using 50-100nm diameter perpendicular magnetic tunnel junctions was recently reported in the IEEE Sensors Journal. The paper demonstrates the magnetic field sensing principle, patented by Spintec in 2020, while also describing possible read-out methods and their associated signal conditioning electronics. Improvements over conventional […]
