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…
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…
Ultrasound evidence for a two-component superconducting order parameter in SrRuO
S. Benhabib, C. Lupien, I. Paul +9
The quasi-2D metal SrRuO is one of the best characterized unconventional superconductors, yet the nature of its superconducting order parameter is still highly debated. Thi…
Precession-free domain wall dynamics in compensated ferrimagnets
E. Haltz, J. Sampaio, S. Krishnia +3
One fundamental obstacle to efficient ferromagnetic spintronics is magnetic precession, which intrinsically limits the dynamics of magnetic textures, We demonstrate that the domain…
