Observation of the orbital Nernst effect
Yuto Masuda, Takamasa Hirai, Daegeun Jo +5
The Nernst effect, which converts a temperature gradient into a transverse charge current, is fundamental to thermoelectrics. Its spin analogue, the spin Nernst effect, enables the…
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…
Spin-Orbital Hall Nano-Oscillators using PtCr/NiFe
Utkarsh Shashank, Akash Kumar, Daegeun Jo +11
The orbital Hall effect provides a promising route for generating angular-momentum currents beyond conventional spin Hall physics. PtCr alloys exhibit unusually large current-induc…
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…
Theoretical study of orbital torque: Dependence on ferromagnet species and nonmagnetic layer thickness
Daegeun Jo, Peter M. Oppeneer
The manipulation of magnetization in ferromagnetic metals (FMs) through orbital torque (OT) has emerged as a promising route for energy-efficient magnetic devices without relying o…
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,…
