Ferromagnetic resonance in one- and two-layer films of iron garnets of mixed composition

Epitaxial films of iron garnets of some mixed compositions are considered in the paper aiming at the determination methodology development for magnetic parameters of one-layer and two-layer iron garnet films by the ferromagnetic resonance method. The investigation of the thin sub-layer influence on magnetic parameters of a film is also the aim of the paper. As a result some features of the ferromagnetic resonance in two-layer iron garnet films, connected with effects of the interlayer interaction have been detected for the first time. New methodologies for the otbtaining of the reliable information about magnetic and relaxation properties of iron garnet films have been developed and their comparative analysis has been held.
