Abstract

A systematic study of the frequency dependence, from 26.5 to 60 GHz, of the ferromagnetic resonance linewidth for technologically useful nickel ferrites is presented in a wide range of compositions for both single-crystal and polycrystalline samples. The FMR linewidth of the polycrystalline samples appears to be virtually independent of the frequency. Theoretical approaches are applied in our range of frequencies providing a justification of our experimental results.
