E. A. Vilkov,Gennady M. Mikhailov,S. A. Nikitov,Ansar R. Safin,M. V. Logunov,Vladislav N. Korenivskii,S. G. Chigarev,L. A. Fomin +7 more
TL;DR: In this paper, the dynamics of the magnetic moment averaged over an ensemble of nonequilibrium spin-injected electrons in a ferromagnetic junction is considered with allowance for the exchange interaction, as well as the interaction with an external electromagnetic field and a thermostat.

sd-Exchange emission in ferromagnetic junctions
TL;DR: In this paper, the authors theoretically analyzed the spin-injection emission in a ferromagnetic junction at terahertz frequencies and showed that the efficiency of the emission caused by the sd-exchange interaction of the injected spin in which the electromagnetic field is involved strongly depends on the orientation angle of the magnetization of the active region relative to the magnetisation direction of the injecting region.

Dynamics of Spatially Inhomogeneous Spin Polarization of Nonequilibrium Conduction Electrons in Magnetic Transitions
E. A. Vilkov,Gennady M. Mikhailov,S. A. Nikitov,Ansar R. Safin,M. V. Logunov,Vladislav N. Korenivskii,S. G. Chigarev,L. A. Fomin +7 more
TL;DR: In this paper, it was shown that the anisotropy of the radiation medium is determined not only by anisotropic properties of the sd-exchange tensor, but also by the electron impulse derivatives of this tensor.
