| Abstract: | The resonance magnetization dynamics in multilayer nanostructures exposed to transverse and longitudinal magnetic fields is investigated with allowance for biquadratic exchange coupling between the magnetic moments of neighboring layers. It is found that the crystallographic magnetic anisotropy leads to the appearance of a minimum on the field dependence of the resonance frequency for the “acoustic” mode and the accompanying maximum in the magnetic susceptibility. |
