Electric excitation of spin resonance in altermagnetic and antiferromagnetic conductors
R. Ramazashvili, V. Shablenko, Ya. B. Bazaliy
We predict electric-dipole spin resonance (EDSR) in altermagnetic conductors: in a magnetic field , perpendicular to the magnetization axis, an AC electric field…
Electron states, bound to a texture in a Néel antiferromagnet
Naïmo Davier, Revaz Ramazashvili
We study electron states, bound to topological textures such as skyrmions and domain walls in a Néel antiferromagnet. In certain limits, we find the dependence of bound states on t…
Texture-induced spin-orbit coupling and Skyrmion-electron bound states in a Néel antiferromagnet
Naïmo Davier, Revaz Ramazashvili
We derive effective-mass electron Hamiltonian for a Néel antiferromagnet in the presence of a smooth texture of the staggered magnetization. For certain locations of electron band…
Closed-loop electric currents and non-local resistance measurements with wide F/I/N tunnel contacts
Ya. B. Bazaliy, R. R. Ramazashvili
Lateral spin valves are used to generate and characterize pure spin currents. Non-local voltage measured in such structures provides information about spin polarization and spin de…
Experimental evidence for Zeeman spin-orbit coupling in layered antiferromagnetic conductors
R. Ramazashvili, P. D. Grigoriev, T. Helm +9
Most of solid-state spin physics arising from spin-orbit coupling, from fundamental phenomena to industrial applications, relies on symmetry-protected degeneracies. So does the Zee…
Zeeman spin-orbit coupling in antiferromagnetic conductors
Revaz Ramazashvili
This article is a brief review of Zeeman spin-orbit coupling, arising in a low-carrier commensurate Néel antiferromagnet subject to magnetic field. The field tends to lift the dege…
