Effects of antiferromagnetic coupling and pinning on domain wall dynamics in synthetic ferrimagnets
Sougata Mallick, Nicolas Reyren, André Thiaville +4
Domain wall (DW) dynamics in antiferromagnetic (AFM) systems offer the advantages over their ferromagnetic counterparts of having faster and more energy efficient manipulation due…
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…
Current-induced nucleation and motion of zero field skyrmion
Sougata Mallick, Sujit Panigrahy, Gajanan Pradhan +1
We study the stabilization and electrical manipulation of skyrmions in magnetic ultrathin films in the absence of an applied magnetic field. We show that this requires an increased…
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…
Driving skyrmions with low threshold current density in Pt/CoFeB thin film
Brindaban Ojha, Sougata Mallick, Sujit Kumar Panigrahy +4
Magnetic skyrmions are topologically stable spin swirling particle like entities which are appealing for next generation spintronic devices. The expected low critical current densi…
Degenerate skyrmionic states in synthetic antiferromagnets
Mona Minakshee Manjaree Bhukta, Braj Bhusan Singh, Sougata Mallick +2
Topological magnetic textures, characterized by integer topological charge , are potential candidates in future magnetic logic and memory devices, due to their smaller size and…
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…
A novel chiral spin texture: Antiferromagnetic Skyrmionium
Mona Minakshee Manjaree Bhukta, Abhilash Mishra, Gajanan Pradhan +3
Exotic spin textures viz. chiral domain wall, vortices, skyrmion, skyrmionium, etc. have recently emerged as active field of research because of their potential applications in hig…
Size and shape of skyrmions for variable Dzyaloshinskii-Moriya interaction and uniaxial anisotropy
Aroop Kumar Behera, Swapna Sindhu Mishra, Sougata Mallick +2
We have performed micromagnetic simulations to study the formation of skyrmions in ferromagnetic elements with different shapes having perpendicular anisotropy. The strength of Dzy…
