Optical access of magnetic tunnel junctions for future hybrid spintronic–photonic memory circuits (August 24th, 2020)
We demonstrate in this study a fabrication process that enables the realization of a top transparent conductive electrode of magnetic tunnel junctions (MTJs), building blocks of magnetic random access memories (MRAMs). This work opens up the realization of future and faster nonvolatile memories based on hybrid spintronic photonic circuits. This new process has been electrically […]

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. […]

The intense recent research on skyrmions has focused on multilayers of classical magnetic materials (Co, CoFeB, Fe…). In this work, the authors explore skyrmions in van der Waals bi-dimensional magnets, a new type of magnetic material in the broad family of 2D materials. Using ab initio and Monte Carlo calculations, they demonstrate that skyrmions should […]
Read moreSpin Transfer Torque Magnetic Tunnel Junction for Single Event Effects mitigation in IC Design (July 23rd, 2020)
Due to its good radiation effects tolerance and its inherent non volatility, Spin-Transfer Torque Magnetic Tunnel Junction (STT-MTJ) is considered as a promising candidate for high-reliability electronics. A radiation tolerant circuit design suitable for space application is proposed in this study. Radiation effects research on semiconductors has been pursued since the 1960s becoming an extremely […]
Read moreMagnetic skyrmions are topologically protected spin textures of great interest for nanoscale information storage and processing. However, stabilizing small skyrmions without applying an external magnetic field remains challenging. This study employs a thin ferromagnetic layer exchange-biased by an antiferromagnetic film to stabilize ferromagnetic skyrmions down to 30 nm in diameter, at zero magnetic field. In […]

Layered magnetic topological insulators are candidate to unveil novel electronic phases controlled by the magnetization. In MnBi4Te7, we evidenced a transition from an antiferromagnetic to a ferromagnetic-like metamagnetic state, possibly realizing the quantum anomalous Hall regime in ultra-thin films above 1K. 3D topological insulators ideally have an insulating bulk and 2D gapless topological surface states […]

Topological insulators (TI) represent a new class of insulating materials hosting metallic surface states. Moreover, those surface states exhibit a Dirac cone energy dispersion where the strong spin-orbit coupling leads to a helical spin texture at the Fermi level. This property can be exploited to detect spin currents in conventional semiconductors like silicon or germanium. […]

Cécile Naud, Caroline Thébault, Marie Carrière, Yanxia Hou, Robert Morel, François Berger, Bernard Dieny, Hélène Joisten, Nanoscale Advances, RSC (2020). Cancer treatment by magneto-mechanical effect of particles (TMMEP) is a growing field of research. The principle of this technique is to apply a mechanical force on cancer cells in order to destroy them thanks to […]
