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…
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…
Role of interfaces in the biased composition of TbFe(Co) thin films
E. Haltz, R. Weil, J. Sampaio +9
Ferrimagnetic TbFe or TbFeCo amorphous alloy thin films have been grown by co-evaporation in ultra-high vacuum. They exhibit an out-of-plane magnetic anisotropy up to their Curie t…
Mechanical tunning of adhesion through micro-patterning of elastic surfaces
Christophe Poulard, Frédéric Restagno, Raphaël Weil +1
We present an investigation of the role of micropatterning on adhesion properties at soft deformable polydimethylsiloxane (PDMS)/ acrylic adhesive interfaces. Contrary to what has…
