Interplay of nonrelativistic and relativistic spin splittings in altermagnets
Daegeun Jo, Peter M. Oppeneer, Mohsen Yarmohammadi
Despite their compensated magnetic moments, altermagnets (AMs) exhibit nonrelativistic spin splitting (NRSS) that offers routes to spintronic functionality without relying on relat…
Giant perpendicular Edelstein polarization in 2D compensated magnets via bichromatic Floquet driving
Mohsen Yarmohammadi, Daegeun Jo, Marco Berritta +3
While unconventional -wave magnets can generate nonrelativistic Edelstein polarizations, spin-group symmetries strictly forbid these responses in unconventional magnets with hig…
Unconventional orbital currents and torques due to ferro-rotational orbital textures
Daegeun Jo, Peter M. Oppeneer
Orbital angular momentum transport has emerged as a promising route for manipulating magnetic devices, yet its generation has largely relied on the conventional orbital Hall effect…
Electrotoroidicity: New Paradigm for Transverse Electromagnetic Responses
Kai Du, Daegeun Jo, Xianghan Xu +7
The exploration of transverse electromagnetic responses in solids with broken spatial-inversion (I) and/or time-reversal (T) symmetries has unveiled numerous captivating phenomena,…
Weak Ferromagnetism in Altermagnets from Alternating -Tensor Anisotropy
Daegeun Jo, Dongwook Go, Yuriy Mokrousov +3
Altermagnets are magnetic materials with antiferromagnetic spin ordering but exhibit ferromagnetic properties. Understanding the microscopic origin of the latter is a central probl…
Gigantic current control of coercive field and magnetic memory based on nm-thin ferromagnetic van der Waals Fe3GeTe2
Kaixuan Zhang, Seungyun Han, Youjin Lee +11
Controlling magnetic states by a small current is essential for the next-generation of energy-efficient spintronic devices. However, it invariably requires considerable energy to c…
