Bringing a ferromagnetic layer to resonance creates non-equilibrium magnetization dynamics which generates a spin current. The spin current propagates from the ferromagnet into a neighboring layer if permitted by the interface. This is equivalent to saying that the air-flow generated by rotating the blades of a fan can propagate in a neighboring room if the […]

Ces structures magnétiques nanométriques ont été observées à températures ambiante dans des matériaux compatibles avec l’industrie électronique. Ces résultats font sauter un verrou important quant à l’utilisation des skyrmions comme vecteur d’information à l’échelle nanométrique dans nos ordinateurs.

During writing of Thermally Assisted Switching Magnetic Random Access Memory (TAS-MRAM), the torque due to a voltage pulse may be used to help writing. As part of collaboration between Spintec and Crocus Technology, we brought out that most of the influence of the spin transfer torque is exerted during the last part of the voltage […]

Magnetic Origami

Magnetic Origami Magnetic devices made from the same thin film and subjected to the same electric excitation switch opposite to each other due to their different shape. Mihai MIRON The magic about the art of paper folding is that from the same sheet of paper one can create so many different objects. Unfortunately, the functionality […]

Giant enhancement of magnetic effect will benefit spintronics Researchers from Spintec have demonstrated that coating a cobalt film in graphene doubles the film’s perpendicular magnetic anisotropy (PMA), so that it reaches a value 20 times higher than that of traditional metallic cobalt/platinum multilayers that are being researched for this property. In a material with a […]

Spintec développe une mémoire STT-MRAM dix fois plus rapide que les produits annoncés pour 2016 chez Samsung ou Intel. Sa vitesse d’écriture est inférieure à la nanoseconde, contre 5 à 10 nanosecondes habituellement. La différence tient au processus de déclenchement du pulse d’écriture. Spintec l’accélère grâce à deux polariseurs d’aimantation orthogonale, placés de part et […]

Les mémoires magnétiques à base de jonctions tunnel magnétiques appelées Spin-Transfer-Torque Random Access Memories (STT-MRAM) suscitent un intérêt considérable pour la micro-électronique grâce à leurs avantages combinés de non-volatilité, densité, vitesse, endurance. Dans ce travail, une nouvelle variété de telles mémoires a été développée offrant une vitesse d’écriture sub-ns appropriée pour les applications de type […]

TRAINING BY RESEARCH

Training by research: doctoral and post doctoral training   Training students and professionals through research is one of the SPINTEC key missions. Ensuring the highest standard of scientific and human management towards the early stage researchers (PhDs and post docs) is a commitment we share within all INAC teams.   SPINTEC students belong to 2 […]

Magnetic sensors

Thematic overview Spintec was originally heavily involved in read heads for disk drive, yet this activity all but vanished due to the strong consolidation of the industry, now with only two players with strong internal R&D capabilities. The technologies used consumer applications sensors remain relatively simple and the industry is extremely conservative, which limits the […]
