TOPOLOGICAL SPINTRONICS

Overview

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 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).
