The optimization of the epitaxial growth of La 0.7 Sr 0.3 MnO 3 (LSMO) films was carried out. The transport properties and the ferromagnetic resonance line was measured. LSMO film had a width of the FMR line 200Oe, and the Curie temperature of 350K. The magnetic resonance spectra (FMR) were taken in order to assess the quality of films and the definition of effective parameter generating spin current.
