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…
