Magnetic spintronic memory called STT-MRAM have recently entered in volume production at major microelectronic foundries. The research in this area is now focused on preparing the future memory generations with higher capacity, higher speed, lower power consumption, wider range of operating temperature. To conduct this type of research, it is important to be able to […]

MRAM is a type of nonvolatile memory that stores the binary information through the magnetic configuration of its main building block: the Magnetic Tunnel Junction (MTJ). In the last decade, the use of perpendicular anisotropy existing at the tunnel barrier interface, allowed to improve MRAM manufacturability. However, the thermal sensitivity of the interfacial anisotropy is […]

L’Usine Nouvelle, magazine dédié à l’industrie, met en avant la spintronique avec une série d’articles, dont deux sur des startups de SPINTEC: La France est au top niveau mondial dans la spintronique [Made in France] La pépite Antaïos réinvente la mémoire magnétique Hprobe, la pépite française qui veut accélérer le test de mémoires et capteurs […]

Hprobe passe à la vitesse supérieure. Après avoir levé 300 000 euros en avril 2018, la start-up issue de SPINTEC et spécialiste du test magnétique de composants semi-conducteurs vient de boucler un deuxième tour de table de 2 millions d’euros. Parmi les investisseurs figurent le fond d’investissement taïwanais ITIC et l’équipementier japonais de production de […]

We propose an original concept of spintronic memristor based on the angular variation of the tunnel magnetoresistance (TMR) of a nanopillar comprising several magnetic layers. We have experimentally developed the appropriate magnetic free layer and integrated it in a full nanosized magnetic tunnel junction pillar. In parallel, we developed a model describing the magnetization dynamics […]

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, […]

Increasing the thermal budget beyond 400°C of magnetic random access memory (MRAM) cells is a major goal to allow for seamless conventional electronics integration. At these temperatures significant material diffusion can destroy the interface properties of new generation perpendicular magnetization stacks targeting technology nodes below 20nm. This study highlights the origin in the improvement obtained […]

The conceptual proposal for a so-called race-track three-dimensional data storage device based on domain walls in a dense array of vertical wires, revived the attention on cylindrical magnetic nanostructures. While mostly nanowires have been considered so far, nanotubes, i.e. a shell with an empty core, would open the door to core-shell structures, whose interfaces could […]

This study discuss the shift observed in spintronics from the current-perpendicular-to-plane geometry towards lateral geometries, illustrating the new opportunities offered by this configuration. The possibility to combine ultrathin magnetic and non-magnetic layers allowed creating hetero-structures whose dimensions are smaller than the characteristic lengths of the spin-dependent transport. This has notably led to the discovery of […]

We have developed arrays of innovative magnetic nanotweezers or “nanojaws” on silicon wafers, by a top-down approach using the fabrication techniques of microelectronics. The mechanical manipulation of micro- and nanometric objects relies on constantly evolving techniques, which are of great interest to the life sciences and biotechnologies. Numerous biomedical studies, either fundamental or applied to […]
