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.

Research topics

Spin-Charge interconversion

Nanostructure made of a horizontal stripe of spin Hall effect material, with two vertical ferromagnetic electrodes to probe the spin accumulation or to inject spin currents. The nanostructure allows probing both the charge-to-spin (left) and spin-to-charge (right) conversions due to the spin-orbit coupling.

Control of magnetization

Nanostructure possessing NiFe nanowires, in which magnetic domain walls can propagate. When located at the vicinity of the Cu nanowire, the domain wall can be used to inject or detect pure spin currents.

Ballistic spin currents

The ballistic surface Dirac fermions in a 3D topological insulator propagate on the cristal faces of a quantum wire. The well-defined cross section gives flux-periodic Aharonov-Bohm oscillations of the resistance, due to quantum interference, for a magnetic induction applied parallel to the nanowire. The spin-helical surface modes offer new possibilities to build quantum spintronics devices of simple geometry, either for dissipationless long-range interconnects or local spin filtering controled by a magnetic field or an electrostatic gate.
