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…
Field-free Josephson diode effect in a d-wave superconductor heterostructure
Hamed Vakili, Moaz Ali, Alexey A. Kovalev
We study superconductor/normal region/superconductor (S|N|S) Josephson junction formed using superconductors with d, d + id', and d + is superconducting pairings. We show that the…
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…
