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) s oj 2 composition resulted from air high-temperature annealing are investigated. On the basis of experimental data analysis was shown that the annealing at T a =1100°C, t a >8 hrs and T a =1150°C, 1200°C, t a =2?10 hrs 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.
