FMR study on some magnetic granular films

We have measured the angular dependence of the ferromagnetic resonance (FMR) spectra for two systems of magnetic granular films: Ag-Co and Ni-SiO/sub 2/. In these two systems, the concentration of the magnetic component was varied to tune the magnetic properties, which were reflected from the FMR spectra. Our results have shown that the angular dependences of resonance field and the line width of these samples are changed significantly with the concentration of magnetic component.
