ANTIFERROMAGNETIC SPINTRONICS

Overview

Antiferromagnetic materials could represent the future of spintronics thanks to the interesting features they combine: they are robust against perturbation due to magnetic fields, produce no stray fields, display ultrafast dynamics and generate large magneto-transport effects. In this team, research efforts are being invested in unraveling spin-dependent transport specifities of antiferromagnets. For a review of  the team latest achievements, please follow this talk.

Research topics

Spin and charge transport

Whether spin and charge currents can be injected, transmitted and converted in antiferromagnetic materials, how subsequent variations can be detected, and what is the actual influence of the magnetic order vs. defects are some of the thrilling challenges being addressed, whether it be magnons, single electrons or Cooper pairs.

Nanomagnetism

To what extent and how the magnetic properties of antiferromagnetic materials shall and can be adjusted for use as functional materials in spintronic applications are some of the questions addressed in this activity, whether it be interfacial spin structures or spin textures like skyrmions.

Sub-THz dynamics

How sub-THz dynamics of antiferromagnets can promote spin pumping, and with what efficiency with respect to the damping parameter and to the transfer of angular momentum from the antiferromagnet are some of the exciting challenges addressed in this activity.

  • A fluctuating magnetic order allows more spins to pass through an interface (February 26th, 2016)
    Bringing a ferromagnetic layer to resonance creates non-equilibrium magnetization dynamics which generates a spin current. The spin current propagates from the ferromagnet into a neighboring layer if permitted by the interface. This is equivalent to ...
