In this paper, the temperature and magnetic field dependence of permeability, $\mu$, in Fe 100-x - Bx ( x = 18, 20, 22), Fe 78B 14Si 8 and Fe 62Ni 16B 14Si 8 are studied. After annealing up to Curie temperature, Fe 80B 20 and Fe 78B 22 alloys become crystalline, while other alloys remain amorphous. The Curie temperatures were measured. The DC magnetic field dependence of the permeability shows that the approach to saturation is modified by annealing.
