Reversal of the skyrmion topological deflection across ferrimagnetic angular momentum compensation
L. Berges, R. Weil, A. Mougin +1
Due to their non-trivial topology, skyrmions describe deflected trajectories, which hinders their straight propagation in nanotracks and can lead to their annihilation at the track…
Evidence of Strong Dzyaloshinskii-Moriya Interaction at the Cobalt/Hexagonal Boron Nitride Interface
Banan El-Kerdi, André Thiaville, Stanislas Rohart +4
The Dzyaloshinskii-Moriya interaction (DMI) and perpendicular magnetic anisotropy (PMA) were measured on four series of Co films (1-2.2 nm thick) grown on Pt or Au and covered with…
Size-dependent mobility of skyrmions beyond pinning in ferrimagnetic GdCo thin films
Léo Berges, Eloi Haltz, Sujit Panigrahy +5
Magnetic skyrmions are swirling magnetic textures that can be efficiently driven with spin-orbit torques with a deflected trajectory. However, pinning slows skyrmions down and alte…
Domain wall dynamics in antiferromagnetically-coupled double-lattice systems
Eloi Haltz, Sachin Krishnia, Léo Berges +2
In ferromagnetic materials, the rich dynamics of magnetic domain walls (DWs) under magnetic field or current have been successfully described using the well-known q-ϕ analytical mo…
Spin-orbit coupling in single layer ferrimagnets: direct observation of spin-orbit torques and chiral spin textures
Sachin Krishnia, Eloi Haltz, Léo Berges +7
We demonstrate that effects of spin-orbit coupling and inversion asymmetry exist in a single GdFeCo ferrimagnetic layer, even without a heavy metal interface. We use electric trans…
Spin pumping as a generic probe for linear spin fluctuations: demonstration with ferromagnetic and antiferromagnetic orders, metallic and insulating electrical states
O. Gladii, L. Frangou, G. Forestier +12
We investigated spin injection by spin pumping from a spin-injector(NiFe) into a spin-sink to detect spin fluctuations in the spin-sink. By scanning the ordering-temperature of sev…
