Opis:: Spin wave modes in antiferromagnetically exchange-coupled magnetic double layers are analyzed theoretically. The considered structure is assumed to be covered by a nonmagnetic metallic layer. The spin wave frequencies and spin wave life times are determined from the macroscopic description based on the Landau-Lifshitz-Gilbert equation, which includes the torque due to spin pumping to the cap layer.

Opis:: Taking into account the available experimental results, we model the electronic properties and current-voltage characteristics of a ferromagnet-semiconductor junction. The Fe/GaAs interface is considered as a Fe/(i-GaAs)/n⁺-GaAs/n-GaAs multilayer structure with the Schottky barrier. We also calculate numerically the current-voltage characteristics of a double-Schottky-barrier structure Fe/GaAs/Fe, which are in agreement with available experimental data. For this structure, we have estimated the spin current in the GaAs layer, which characterizes spin injection from the ferromagnet to the semiconductor.
