Abstract
We have used the X-band ferromagnetic resonance (FMR) spectra of granular Co5Cu95 ribbons, as cast, and heat treated as a function of temperature, in order to study their magnetic and structural properties. From a model derived for the temperature dependence of the FMR linewidth, the mean diameter and effective anisotropy constant (Keff) of the magnetic grains were obtained. Enhanced values of Keff in comparison to the bulk materials, and also a decrease with increasing mean diameter, have been found. Our results indicate a large influence of the surface magnetic anisotropy in the smaller grains and also on the behavior of the resonance field and linewidth.
