Descrição
Resumo:[EN] In the presently work ferromagnetic resonance (FMR) of metallic glasses in microwires form of composition (FexCo1-x)72.5 Si12.5 B15 has been measured. The ferromagnetic resonance frequency of amorphous magnetic microwires has been obtained from power absorption measurements in the microwave frequency range. The experimental technique here employed consists on the replacement of the dielectric of a coaxial transmission line by the sample to be measured. From the evolution of the resonance frequency with a dc applied magnetic field, the anisotropy field of the microwires has been deduced, and successfully compared to that obtained from quasi-static hysteresis loops.
