Abstract
The variations of FMR spectra, domain structure and basic magnetic parameters the thin epitaxial ferrite-garnet films of (Y,Sm,Lu,Ca)3(Fe,Ge)5O12 composition resulted from air high-temperature annealing are investigated. On the basis of experimental data analysis was shown that the annealing at Ta = 1100°C, ta>8 hrs and Ta=1150°C, 1200°C, ta=2-10hrs leads to creation of the magnetic transitional layer at the film-substrate boundary. The basic magnetic parameters of films and transitional layers are determined from the FMR spectra. The nature and the formation mechanism of the magnetic transitional layer are discussed.
