Abstract: Temperature dependence of attenuation of magnetic spin precession in two-layer structures with a Pt top layer based on a La$_{0.7}$Sr$_{0.3}$MnO$_{3}$ (LSMO) epitaxial manganite film is studied by measuring the width of a ferromagnetic resonance (FMR) line. Ferromagnetic resonance in thin ferromagnetic manganite films is used for the creation of a spin current at the interface between the metallic and ferromagnetic layers. A significant increase in a width of a line in FMR spectrum in two-layer structures due to generation of a spin current, heterogeneity of a ferromagnetic layer, two-magnon scattering, and eddy current is discussed.

Keywords: Spin Current, Ferromagnetic Resonance (FMR), Eddy Currents, Ferromagnetic Layers, Epitaxial Manganite Films.
