Skyrmion inertia in synthetic antiferromagnets
Sujit Panigrahy, Sougata Mallick, Joao Sampaio +1
We describe the dynamics of magnetic skyrmions in synthetic antiferromagnets (SAF), with a finite interlayer coupling. Due to the opposite gyrovector of the skyrmions in the two SA…
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…
Domain wall propagation by spin-orbit torques in in-plane magnetized systems
Ryuhei Kohno, João Sampaio, Stanislas Rohart +1
The effect of damping-like spin-orbit torque (DL SOT) on magnetic domain walls (DWs) in in-plane magnetised soft tracks is studied analytically and with micromagnetic simulations.…
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…
Velocity enhancement by synchronization of magnetic domain walls
Aleš Hrabec, Viola Křižáková, Stefania Pizzini +4
Magnetic domain walls are objects whose dynamics is inseparably connected to their structure. In this work we investigate magnetic bilayers, which are engineered such that a couple…
