We propose the concept of a core-shell composite structure coupled antiparallel via dipolar interaction, as the storage layer in perpendicular-shape-anisotropy magnetic random access memory (PSA MRAM). Benefits compared with a standard PSA MRAM include a reduced write time and the stray field. CoFeB core with a Co shell (height 8 nm; diameters 14 and 20 […]

Context Non-volatile memories (NVMs) offer several advantages for Multiply-Accumulate (MAC) operations in Artificial Intelligence (AI) applications. The first and key advantage is a reduced power consumption: NVMs consume less power compared to traditional volatile memories (like SRAM and DRAM) because they do not require power to maintain their state. This can lead to significant energy […]

Magnetic skyrmions are magnetic nanobubbles which are envisioned as bits of informations in our computers. A team from the Spintec laboratory in Grenoble has demonstrated that they can be moved by electric current at record speeds, up to 900 m/s, in antiferromagnetic stacks. These results hold promise for the use of skyrmions to store and […]

By using THz spintronic emission, we could study the spin-charge conversion mechanisms in 2D materials. High crystalline quality 2D materials are grown by molecular beam epitaxy on large area and CoFeB is deposited on top using soft UHV sputtering to obtain sharp interfaces. Such model system allows us to identify and quantify the spin-charge conversion […]

Candidate with mandatory University Master degree with following profile: Physics, Engineering, Material Science […]

Scientists from an international consortium have demonstrated experimentally and theoretically the altermagnetic character of the material Mn5Si3, proving the incomparable advantage of this type of zero-magnetization magnetic phase: the strong spintronic effects associated with it are based on non-relativistic physics. Real space: Magnetic and crystalline structure of Mn5Si3. Reciprocal space: shifts in the electronic bands […]

In the framework of the French-German laboratory association between SPINTEC and the IFW Dresden (CNRS International Research Project « SPINMAT »), and in collaboration with the C2N institute and the university of Würzburg, a novel plateform was implemented to reveal the non-hermitian topology of scalable quantum electronic circuits. It opens some new perspectives to realize […]
