TOPOLOGICAL SPINTRONICS



Research team Topological spintronics, within the Concepts group


A team at SPINTEC in Grenoble has demonstrated thermally stable and electrically switchable Spin Transfer Torque MRAM (STT-MRAM) of diameter down to 4nm. Among the various technologies of non-volatile memories, STT-MRAM gathers a unique combination of assets: non-volatility, write speed (3-30ns), density (4Gbit demonstrated by Hynix/Toshiba), low consumption (a few tens of fJ/write), and very […]

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 […]

Spin orbit torques allow to move efficiently DW in tracks made of ferromagnetic/spin Hall effect bilayer. Domain wall (DW) detection is then of great importance. In this letter, we demonstrate a detection method, based on the ability for a ferromagnetic nanowire, in which a DW is pinned, to inject or detect a pure spin current. […]

GeTe has been predicted to be the father compound of a new class of multifunctional materials: ferroelectric Rashba semiconductors. In that sense, they are expected to display a coupling between spin-dependent k-splitting and ferroelectricity, thus allowing an electrical control of spin-to-charge conversion phenomena in spintronics. This paper reported the epitaxial growth of Fe/GeTe(111) heterostructures by […]

OISO – An ANR project

The ANR project OISO (OxIde-based SpinOrbitronics) explores the potential of transition metal oxide (TMO) perovskites for SpinOrbitronics. SpinOrbitronics exploits the spin-orbit coupling (SOC) to obtain spin currents without ferromagnets (FM), more efficient torques to switch magnetization and reduced heat dissipation for low power scalable devices. TMO constitute a material platform of structurally well-matched compounds including […]

At the interface between the strontium titanate and the lanthanide aluminate forms a 2 dimensional electron system. By using a dynamical spin injection technique, we were able to demonstrate a record conversion yield between spin and charge current in this system, moreover that is tunable in amplitude and sign by an electrostatic gate, a premiere. […]

We have demonstrated the spin-to-charge interconversion by Rashba coupling at the interface between two light materials: iron and germanium which is compatible with today’s CMOS technology. This result constitutes the first step towards the fabrication of a spin transistor based on the spin-orbit coupling. The spin-orbit coupling, relating the electron spin and momentum, has long […]

Magnonic is an emerging research field, which aims at exploiting the transport of pure spin current in magnetic materials. The elementary excitations are the propagating spin-waves, also called magnons, which are bosonic quasiparticles. The advantages over conventional electronic devices are a significant reduction in energy consumption thanks to the absence of Joule heating, as well as new features taking […]
