Thermomagnonic Torques in Insulating Altermagnets
Edward Schwartz, Hamed Vakili, Alexey A. Kovalev
We develop a symmetry-controlled theory of anisotropic thermomagnonic torques in insulating altermagnets. We identify a spin-splitter magnonic torque linked to thermally generated,…
Effect of Magnetic Anisotropy and Gradient-Induced Dzyaloshinskii-Moriya Interaction on the Formation of Magnetic Skyrmions
Adam Erickson, Qihan Zhang, Hamed Vakili +10
Topological spin textures (e.g. skyrmions) can be stabilized by interfacial Dzyaloshinskii-Moriya interaction (DMI) in the magnetic multilayer, which has been intensively studied.…
Spin-orbit torque in a three-fold-symmetric bilayer and its effect on magnetization dynamics
Wuzhang Fang, Edward Schwartz, Alexey A. Kovalev +1
Field-free switching of perpendicular magnetization has been observed in an epitaxial L1-ordered CoPt/CuPt bilayer and attributed to spin-orbit torque (SOT) arising from the cr…
Spin-Transfer Torque in Altermagnets with Magnetic Textures
Hamed Vakili, Edward Schwartz, Alexey A. Kovalev
We predict the existence of anisotropic spin-transfer torque effect in textured altermagnets. To this end, we generalize the Zhang-Li torque to incorporate the symmetry associated…
Room Temperature Magnetic Skyrmions in Gradient-Composition Engineered CoPt Single Layers
Adam Erickson, Qihan Zhang, Hamed Vakili +12
Topologically protected magnetic skyrmions in magnetic materials are stabilized by interfacial or bulk Dzyaloshinskii-Moriya interaction (DMI). Interfacial DMI decays with increase…
Nonreciprocal superfluidlike topological spin transport
Alexey A. Kovalev, Bo Li, Edward Schwartz
We study superfluidlike spin transport facilitated by thermal diffusion of magnetic domain walls, where the positive and negative chiralities of domain walls act as opposite topolo…
