The static and dynamic magnetic properties of Go-rich CoFeZr amorphous
thin films have been investigated versus Fe content. The substitution
of Fe for Co allows to increase the saturation magnetization. It favo
urs also the formation of a perpendicular anisotropy as revealed B-H l
oop and domain structure studies. The pecularities of the high frequen
cy permeability spectra appears to be related to weak stripe structure
