Abstract
Monodomain, polycrystalline hexagonal ferrites (BaFe12O19) and amorphous ribbons (Vitrovac 6025) were measured as a function of frequency with rf magnetic fields from 5 Hz to 13 MHz of various amplitudes. Monodomain ferrites showed the features of the spin rotation magnetization mechanism, while amorphous ribbons showed the low-frequency dispersion generally attributed to domain wall relaxation. However, at relatively high applied fields, a third dispersion is resolved at lower frequencies from domain wall relaxation, which can be attributed to magnetic hysteresis. By using some of the complex impedance formalisms, the relaxation character of domain wall bulging is confirmed, while hysteresis dispersion exhibited a complex behavior.
