The frequency dependence of the permeability of Co- and Fe-rich amorphous ribbons (Vitrovac 6025(R) and Metglas(R) 2605 SC, respectively), submitted to a variety of thermal treatments involving different degrees of crystallization, was measured in the 5 Hz-13 MHz frequency range. The quasi-static initial permeability, /spl mu//sub i/, and the domain wall relaxation frequency, f/sub x/, exhibited an inverse relationship, /spl mu//sub i//spl middot/f/sub x/=constant. These results are interpreted in terms of variations in the average distance between pinning points of domain walls, and the effects of such variations on the vibrational properties of pinned domain walls.
