Our team aims at manipulating spins currents in nanostructures, in particular in quantum materials with Dirac fermions, such as topological insulators or Weyl semimetals, or at oxide interfaces. Some important aspects of future spintronics devices, such as the efficient spin-charge interconversion at interfaces or the ballistic transport of spin states for quantum interconnects, are studied by magneto-transport measurements.
Spin-Charge interconversion by spin Hall effect or Rashba-Edelstein effect, in metals, semiconductors, topological insulators and 2-dimensional electron gas
Control of domain walls and magnetization using spin currents and the spin-orbit coupling
Ballistic helical spin currents in a monocrystalline 3D topological insulator quantum wire, inducing conductance oscillations due to coherent Dirac surface states (Aharonov-Bohm quantum interferences).

- Sub-10nm thermally stable Perpendicular Shape Anisotropy STT-MRAM realized at SPINTEC (March 08th, 2018)
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 ...
- Giant magnetoresistance in lateral metallic nanostructures for spintronic applications (January 22nd, 2018)
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 ...

- Electrical detection of magnetic domain walls by inverse and direct spin Hall effect (August 28th, 2017)
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 ...
- Evidence for spin to charge conversion in GeTe(111), among most read 2016 papers of APL Mater. (August 28th, 2017)
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 ...
