We study theoretically and experimentally the spin pumping signals induced by the resonance of canted antiferromagnets with Dzyaloshinskii-Moriya interaction and demonstrate that they can generate easily observable inverse spin-Hall voltages. Using a bilayer of hematite/heavy metal as a model system, we measure at room temperature the …

En aviation, le flottement ou flutter (de l'anglais flutter « battement des ailes ») est un phénomène de couplage aéroélastique, potentiellement destructeur, entre les forces aérodynamiques et la structure d'un aéronef en vol. Il apparaît généralement à vitesse élevée, ce qui conduit à limiter la vitesse maximale d'un aéronef .
