The influence of the interlayer exchange coupling on magnetic resonance properties of an easy-axis/easy-plane bilayer film structure is investigated theoretically for an arbitrary orientation of a strong external magnetic field. Resonant fields and high-frequency magnetic susceptibility tensor as a function of the field tilt angle (with respect to the film normal) and layer thickness are obtained and analysed. The theoretical results are in good agreement with experimental data for epitaxial iron garnet films.
