Driving skyrmions in flow regime in synthetic ferrimagnets
Sougata Mallick, Yanis Sassi, Nicholas Figueiredo Prestes +11
Despite significant advances in the last decade regarding the room temperature stabilization of skyrmions or their current induced dynamics, the impact of local material inhomogene…
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…
Tunability of domain structure and magnonic spectra in antidot arrays of Heusler alloy
Sougata Mallick, Sucheta Mondal, Takeshi Seki +8
Materials suitable for magnonic crystals demand low magnetic damping and long spin wave (SW) propagation distance. In this context Co based Heusler compounds are ideal candidates f…
Skyrmion Racetrack memory with an antidot
Aroop Kumar Behera, Chandrasekhar Murapaka, Sougata Mallick +2
Skyrmion racetrack memory has a lots of potential in future non-volatile solid state devices. In general such devices require current to nucleate skyrmions via spin transfer torque…
