Abstract

We present the ferromagnetic resonance (FMR) mode characteristics of two ferromagnetically coupled layers. Calculations are given for an applied DC magnetic field perpendicular to the film plane. The analysis predicts the number, positions, intensities and linewidths of the FMR peaks as functions of the coupling strength K. The magnetocrystalline anisotropy was taken to be uniaxial. The model has been applied to experimental results on a NiFe/Ag/Ni system. By comparison with the in-plane DC field case, we found a possible angular dependence of the interfacial coupling constant K.
