| Ferromagnetic resonance was investigated in heterogeneous Co-Cu thin films consisting of randomly oriented fine Co particles embedded in Cu matrix. The experimental spectra are modelled using dynamic susceptibility approach assuming a broad distribution in particle sizes and dipolar interactions between particles. |
