MRAM



Research team MRAM memories, within the Devices group


The European consortium SpintronicFactory, largely supported by the French laboratories Spintec (Grenoble) and the CNRS-Thales Joint Lab (Palaiseau), publishes in the journal Nature Electronics an ambitious roadmap for spintronics. This discipline on the borderline between magnetism and microelectronics is indeed reaching maturity, offering broad prospects for innovation. B. Dieny, I. L. Prejbeanu, K. Garello, P. […]

This work reports the development of perpendicular magnetic tunnel junctions incorporating a stack of Tb/Co nanolayers whose magnetization can be all-optically controlled via helicity-independent single-shot switching. Toggling of the magnetization of the Tb/Co electrode was achieved using either 60 femtosecond-long or 5 picosecond-long laser pulses, with incident fluences down to 3.5 mJ/cm2. Ever since the […]

Atsufumi Hirohata, Keisuke Yamada, Yoshinobu Nakatani, Ioan-Lucian Prejbeanu, Bernard Diény, Philipp Pirro, Burkard Hillebrands Spintronics is one of the emerging fields for the next-generation nanoelectronic devices to reduce their power consumption and to increase their memory and processing capabilities. Such devices utilise the spin degree of freedom of electrons and/or holes, which can also interact […]

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 […]

Spin accumulation phenomena frequently occur in spintronic devices due to the difference of electrical resistivities of spin-up and spin-down electrons in magnetic materials. They are balanced by spin relaxation phenomena. These phenomena take place in a diffusive regime which involves numerous individual scattering events. Consequently, although the time scale of elastic electron scattering in metals […]

COMRAD – An H2020 ITN project

Overview COMRAD is an H2020 ITN projet (2020-2024). It will explore novel routes for the fastest possible and least dissipative magnetic switching in random access devices by bringing together the two disciplines of ultrafast magnetism and spin-orbitronics, creating sub-100 ps stimuli in spin-orbitronics and pushing the latter into a regime beyond the limitations of equilibrium […]

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 […]
