چکیده انگلیسی
Experimental ferromagnetic resonance (FMR) data are presented for CoCu granular films obtained by electron beam codeposition. CoxCu100âx films were prepared for x=10 and 30 and were subsequently submitted to a thermal treatment. For the 10% Co samples one found three main resonance modes, one of them constituting of non-interacting Co particles. External field angular variation and temperature-dependent FMR experiments were proceeded and straight calculations of the involved resonance intensities as well. A strict correlation of the presented FMR data with the previous X-Ray diffraction, magnetization, and particle size investigations was possible. The link between structural changes and magnetic properties of the samples could be verified. For the 30% Co samples a broad resonance line for the in-plane configuration was found, which is characteristic for polycrystalline systems. In the perpendicular configuration a spin wave spectra were present on all samples and one could identify some of the modes as surface modes. These samples with 30% Co become more heterogeneous with increasing thermal treatment.
