Results of the experimental investigation of two-layer films in the Fe–Bi system are presented. It is found that the order of sequential deposition of the magnetic and nonmagnetic layers influences both the character of magnetization process and the magnetic resonance behavior. The obtained results are explained by the formation of a strongly anisotropic sublayer of nanogranular iron in the Bi/Fe film structure.
